g) constellation status. Note Structure and contents of data are specified in Appendix and respectively 3.7.3.2 NASS Channel of Standard Accuracy (CSA) ( ) Note In this section the term NASS refers to all satellites in the constellation Standards relating only to NASS M satellites are ualified accordingly 3.7.3.2.1 Accuracy 3.7.3.2.1.1 Positioning accuracy. The GLONASS CSA position errors shall not exceed the following limits: of the time 99.99 of the time Horizontal position error Vertical position error 28 m (92 ft) 60 m (196 ft) 140 m (460 ft) 585 m (1 920 ft) 3.7.3.2.1.2 Time transfer accuracy. The GLONASS CSA time transfer errors shall not exceed 700 nanoseconds 95 per cent of the time. 3.7.3.2.2 Availability. The GLONASS CSA availability shall be at least 99.64 per cent (global average). 3.7.3.2.3 Reliability. The GLONASS CSA reliability shall be at least 99.98 per cent (global average). 3.7.3.2.4 Coverage. The GLONASS CSA coverage shall be at least 99.9 per cent (global average). Note uidance material on NASS accuracy availability reliability and coverage is given in Attachment D 2007/70/II. szám C a ter Annex 10 — Aeronautical Communications 3 63 23/11/06 3.7.3.2.5 RF characteristics Note Detailed RF characteristics are specified in Appendix 3.7.3.2.5.1 Carrier fre uency Each GLONASS satellite shall broadcast CSA navigation signal at its own carrier frequency in the L1 (1.6 GHz) frequency band using frequency division multiple access (FDMA). Note NASS satellites may have the same carrier fre uency but in this case they are located in antipodal slots of the same orbital plane Note NASS M satellites will broadcast an additional ranging code at carrier fre uencies in the ( ) fre uency band using FDMA 3.7.3.2.5.2 Signal spectrum GLONASS CSA signal power shall be contained within a 5.75 MHz band centred on each GLONASS carrier frequency. 3.7.3.2.5.3 Polari ation. The transmitted RF signal shall be right-hand circularly polarized. 3.7.3.2.5.4 Signal power level. Each GLONASS satellite shall broadcast CSA navigation signals with sufficient power such that, at all unobstructed locations near the ground from which the satellite is observed at an elevation angle of 5 degrees or higher, the level of the received RF signal at the output of a 3 dBi linearly polarized antenna is within the range of 161 dBW to 155.2 dBW for all antenna orientations orthogonal to the direction of propagation. Note The power limit of d is based on the predetermined characteristics of a user antenna atmospheric losses of d and an error of an angular position of a satellite that does not exceed one degree (in the direction causing the signal level to increase) Note NASS M satellites will also broadcast a ranging code on with sufficient power such that at all unobstructed locations near the ground from which the satellite is observed at an elevation angle of degrees or higher the level of the received RF signal at the output of a d i linearly polari ed antenna is not less then d for all antenna orientations orthogonal to the direction of propagation 3.7.3.2.5.5 Modulation 3.7.3.2.5.5.1 Each GLONASS satellite shall transmit at its carrier frequency the navigation RF signal using a BPSKmodulated binary train. The phase shift keying of the carrier shall be performed at S-radians with the maximum error 0.2 radian. The pseudo-random code sequence shall be repeated each millisecond. 3.7.3.2.5.5.2 The modulating navigation signal shall be generated by the Modulo-2 addition of the following three binary signals:
