c) reliability — at least 99.79 per cent (single point average). 3.7.3.1.4 Coverage The GPS SPS shall cover the surface of the earth up to an altitude of 3 000 kilometres. Note uidance material on PS accuracy availability reliability and coverage is given in Attachment D 3.7.3.1.5 Radio fre uency (RF) characteristics Note Detailed RF characteristics are specified in Appendix 3.7.3.1.5.1 Carrier fre uency. Each GPS satellite shall broadcast an SPS signal at the carrier frequency of 1 575.42 MHz (GPS L1) using code division multiple access (CDMA). Note A new civil fre uency will be added to the PS satellites and will be offered by the United States for critical safety of life applications SARPs for this signal may be developed at a later date 3.7.3.1.5.2 Signal spectrum. The GPS SPS signal power shall be contained within a 12 MHz band (1 563.42 1 587.42 MHz) centred on the L1 frequency. 3.7.3.1.5.3 Polari ation. The transmitted RF signal shall be right-hand (clockwise) circularly polarized. 3.7.3.1.5.4 Signal power level. Each GPS satellite shall broadcast SPS 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 160 dBW to 153 dBW for all antenna orientations orthogonal to the direction of propagation. 3.7.3.1.5.5 Modulation. The SPS L1 signal shall be bipolar phase shift key (BPSK) modulated with a pseudo random noise (PRN) 1.023 MHz coarse/acquisition (C/A) code. The C/A code sequence shall be repeated each millisecond. The transmitted PRN code sequence shall be the Modulo-2 addition of a 50 bits per second navigation message and the C/A code. 2007/70/II. szám Annex 10 — Aeronautical Communications Volume I 23/11/06 3 62 3.7.3.1.6 PS time. GPS time shall be referenced to UTC (as maintained by the U.S. Naval Observatory). 3.7.3.1.7 Coordinate system. The GPS coordinate system shall be WGS-84. 3.7.3.1.8 Navigation information. The navigation data transmitted by the satellites shall include the necessary information to determine:
