Where: d1: Satellite PRN number, with "e" or "E" to the right means got ephemeris data, "v" or "V" to the right means got verified ephemeris data (double check). "E" or "V" also means got satellite time for this channel. d2: Azimuth, in degrees d3: Elevation angle, in degrees d4: SNR (signal to noise ratio), it is ratio-Hz, not dB unit c1: U - Used for position fix, U - Not used for position fix Bad fix code 0 PVT_OK :good fix 2 ILLEGAL_ALT: illegal altitude < -10km or > 17.5km 4 POSITION_JUMP: too big position jump between two epoch (300 miles) 5 ILLEGAL_VELOCITY_OR_ALT: max velocity 951mile 7 TOO_BIG_ACCELERATION max 15m around 1.5g 8 TOO_SMALL_ALTITUDE -10000 m 9 TOO_BIG_ALTITUDE 17,500 m 10 TOO_BIG_PDOP max PDOP 50 11 SATS_BELOW_MASK_ANGLE satellite elevation angle is below mask angle 16 ILL_DEFINED_3D_MATRIX 3X3 matrix can not be inverted in 3D fix 107
