1. Paragraph 1 of Subsection E of Section VI of Annex 8 to the Inspection Protocol shall be superseded by the following provisions:

"1. At the point of entry, the inspection team leader or an authorized representative of such a team shall have the right to confirm, in accordance with the following procedures, that two satellite system receivers provided by the inspected Party are operable:
(a) The first inspection team arriving at each point of entry for which there is at least one associated facility with silo launchers of ICBMs subject to inspection pursuant to paragraph 2, 3, 4, or 6 of Article XI of the Treaty shall have the right to bring to that point of entry two satellite system receivers for the purpose of determining the geographic coordinates of four reference points. These reference points shall be proposed by the inspected Party, shall be within 20 kilometers of the airport of the point of entry, and shall be separated from each other by at least two kilometers.

(b) For the purpose of comparing the reading of one satellite system receiver with the reading of another satellite system receiver, the term "agree" shall mean that the reading of one satellite system receiver differs from the reading of the other satellite system receiver by no more than 12 seconds in both latitude and longitude.

(c) For the purpose of confirming the operability of a satellite system receiver at the point of entry, the term "agree" shall mean that the reading of the satellite system receiver differs from the agreed geographic coordinates of the reference point by no more than 12 seconds in both latitude and longitude.

(d) Determination of the agreed geographic coordinates of reference points used at a point of entry for testing the operability of satellite system receivers shall be conducted in accordance with the following procedures:

(i) At each proposed reference point, the inspection team leader or an authorized representative of such a team, and a member of the in-country escort shall use two satellite system receivers of the inspecting Party and two satellite system receivers of the inspected Party, respectively, to determine geographic coordinate values. The inspected Party shall have the right to substitute a properly operating satellite system receiver for a malfunctioning satellite system receiver provided by the inspected Party. However, no more than two satellite system receivers of the inspected Party may be used for the determination of agreed geographic coordinates for a reference point as described in subparagraphs (d)(ii) and (d)(iii) below;

(ii) If at least three of the four latitude values thus obtained agree with each other, all of these latitude values that agree with at least two other of the four latitude values, shall be averaged, and that average shall be the agreed latitude value of the reference point;

(iii) If at least three of the four longitude values thus obtained agree with each other, all of these longitude values that agree with at least two other of the four longitude values, shall be averaged, and that average shall be the agreed longitude value of the reference point;

(iv) Agreed latitude values and agreed longitude values of the reference point thus obtained shall be recorded to the nearest second and shall be the agreed geographic coordinates of each reference point for the point of entry. A physical description of the reference point shall also be recorded for each reference point. The inspected Party shall provide notification of the determination of agreed geographic coordinates of reference points in accordance with paragraph 28 of Section III of this Protocol;

(v) If agreed geographic coordinates for four reference points cannot be determined after the procedures provided for in this subparagraph have been attempted at no fewer than six proposed points, all agreed coordinates shall be discarded and the procedures provided for in this subparagraph shall be repeated when an inspection team next arrives at this point of entry to conduct an inspection.

(e) The operability of satellite system receivers shall be tested at each point of entry for which there is at least one associated facility with silo launchers of ICBMs subject to inspection pursuant to paragraph 2, 3, 4 or 6 of Article XI of the Treaty. After the baseline data inspection period, operability of the inspected Party's satellite system receivers may be tested at such points of entry, at the discretion of the inspection team leader, for all inspections, except for inspections conducted pursuant to paragraph 8 of Article XI of the Treaty, prior to the departure of the inspection team for the inspection site, at a time agreed by the inspection team leader, and a member of the in-country escort. The time shall be agreed to as soon as possible following the arrival of the inspection team at the point of entry. Testing shall be conducted in accordance with the procedures contained in subparagraph (g) of this paragraph.

(f) Only for inspections conducted during the baseline data inspection period, testing of the operability of the inspected Party's satellite system receivers shall be conducted in accordance with the procedures contained in subparagraph (g) of this paragraph:

(i) either after the inspection team leader has made the designation, provided for in paragraph 15 of Section V of this Protocol, of the type of inspection and inspection site, provided that the use of satellite system receivers is permitted for the designated type of inspection and inspection site; or

(ii) prior to the designation by the inspection team leader, provided for in paragraph 15 of Section V of this Protocol, of the type of inspection and inspection site, at a time agreed to by the inspection team leader and a member of the in-country escort, provided that the inspection team leader declares the inspecting Party's intent to use the satellite system receivers during the first or a sequential inspection for which satellite system receivers may be used.

(g) The operability of each of the inspected Party's satellite system receivers shall be tested at two reference points. These two reference points shall be selected from the four reference points with agreed geographic coordinates. The first reference point shall be selected by a member of the in-country escort, and the second reference point shall be selected by the inspection team leader or an authorized representative of such a team. A member of the in-country escort shall accompany the inspectors to each reference point and shall bring the inspected Party's satellite system receivers to that reference point:

(i) In order for an inspected Party's satellite system receiver to be confirmed to be operable, at each of the two reference points the reading of the satellite system receiver must agree with the agreed geographic coordinates of that reference point;

(ii) If, at either of the two reference points, the reading of an inspected Party's satellite system receiver does not agree with the agreed geographic coordinates of the reference point, a member of the in-country escort shall take another reading using that satellite system receiver. If, after at least two additional attempts, the reading of the satellite system receiver still does not agree with the agreed geographic coordinates, the inspected Party shall replace the satellite system receiver. The replacement satellite system receiver shall be tested in accordance with the procedures contained in subparagraph (g) of this paragraph. The testing of the inspected Party's satellite system receivers shall continue until the inspected Party has provided two satellite system receivers that are confirmed to be operable or until at least four different satellite system receivers have been tested.

(iii) If the inspected Party is unable to provide two satellite system receivers whose operability has been confirmed in accordance with the procedures contained in subparagraph (g) of this paragraph, this fact shall be recorded in the inspection report and the inspection shall proceed.

(h) The inspected Party shall have the right to change the reference points for use in testing the operability of satellite system receivers. No more than two reference points may be changed at any one time, unless otherwise agreed. Agreed geographic coordinates for the new reference point shall be determined using the procedures in subparagraph 1(d) of this subsection when an inspection team next arrives at this point of entry to conduct an inspection after the proposed effective date of a change specified in the notification provided by the inspected Party in accordance with paragraph 29 of Section III of this Protocol. The new reference point shall become effective upon determination of its agreed geographic coordinates."

2. Paragraphs 4, 5, 6, 7, and 8 of Subsection E of Section VI of Annex 8 to the Inspection Protocol shall be superseded by the following provisions:

"4. Upon arrival of the inspection team or subgroup of the inspection team at a silo launcher of ICBMs designated for inspection, inspectors shall use satellite system receivers that have been provided by the inspected Party to determine the geographic coordinates of such silo launcher of ICBMs in accordance with the following procedures:
(a) The specific location where the readings of the satellite system receiver are taken shall be selected by a member of the in-country escort in such a way that, if possible, the designated silo launcher of ICBMs can be seen from that location;

(b) While at this location. specified in accordance with subparagraph (a) of this paragraph, the inspectors shall examine the container and the seal placed on the container to determine whether the seal is intact and whether the container has been tampered with. If there is evidence that the seal has been broken or that the container has been tampered with, this fact shall be recorded in the inspection report and the inspection shall continue;

(c) A member of the in-country escort shall open the container and an inspector shall select one of the two satellite system receivers provided by the inspected Party, the operability of which has been confirmed in accordance with the procedures provided for in subparagraph 1(g) of this Subsection;

(d) For the purpose of comparing the reading of a satellite system receiver with the geographic coordinates of a designated silo launcher of ICBMs, listed in the Agreement on Exchange of Geographic Coordinates and Site Diagrams, the term "agree" shall mean that:

(i) if the geographic coordinates are expressed to the nearest second, the reading of the satellite system receiver differs from the geographic coordinates by no more than 12 seconds in both latitude and longitude;

(ii) if the geographic coordinates are expressed to the nearest minute, the reading of the satellite system receiver differs from the geographic coordinates by no more than 60 seconds in both latitude and longitude;

(e) An inspector shall take readings using the selected satellite system receiver. If the satellite system receiver readings and the geographic coordinates for the location of the designated silo launcher of ICBMs, listed in the Agreement on Exchange of Geographic Coordinates and Site Diagrams, agree, then the silo launcher of ICBMs shall be considered to be the designated silo launcher of ICBMs and the coordinates determined by the satellite system receiver shall be recorded in the inspection report despite the fact that the satellite system receiver readings might also agree with geographic coordinates for the locations of other nearby silo launchers of ICBMs, listed in the Agreement on Exchange of Geographic Coordinates and Site Diagrams. If the satellite system receiver readings at the location selected by a member of the in-country escort do not agree with the geographic coordinates for the designated silo launcher of ICBMs, listed in the Agreement on Exchange of Geographic Coordinates and Site Diagrams, then inspectors shall use the second satellite system receiver. If a satisfactory result cannot be obtained with either of the two satellite system receivers, then a member of the in-country escort shall choose another location closer to the silo launcher of ICBMs where an inspector shall take readings using a satellite system receiver. If, after using both of the satellite system receivers at any of the locations chosen by a member of the in-country escort, inspectors establish that the readings of neither satellite system receiver agree with the geographic coordinates for this designated silo launcher of ICBMs, and the inspectors are thus unable to ascertain that the silo launcher of ICBMs is the designated silo launcher of ICBMs, this fact shall be recorded in the inspection report and the inspection shall continue;

(f) Upon completion of the satellite system receivers' use, a member of the in-country escort, in the presence of inspectors, shall place the satellite system receivers in a container. A representative of the inspection team shall seal the container and provide the container to a member of the in-country escort."

1. The following provisions shall constitute paragraph 28 of Section III of the Inspection Protocol:

"28. Notification of the determination, in accordance with subparagraph 1(d) of Subsection E of Section VI of Annex 8 to this Protocol, of agreed geographic coordinates of reference points used at a point of entry for testing the operability of satellite system receivers, shall be provided by the inspected Party no later than 48 hours after such determination and shall include:
(a) the point of entry;

(b) the date of determination of the agreed geographic coordinates;

(c) the agreed geographic coordinates of each of the reference points; and

(d) a physical description of each of the reference points."

2. The following provisions shall constitute paragraph 29 of Section III of the Inspection Protocol:
