1.3 Performance
Table 1: NEO-M8P performance in different GNSS modes (default: concurrent reception of GPS and GLONASS)
1
Assuming Airborne < 4 g platform
2
50% @ 30m/s for dynamic operation or assuming a 1m baseline in MB mode
3
All satellites at -130 dBm
4
Dependent on aiding data connection speed and latency
5
Demonstrated with a good external LNA
6
Limited by FW for best performance
7
Depends on atmospheric conditions, baseline length, GNSS antenna, multipath conditions, satellite visibility and geometry
8
Measured with 1 km baseline, patch antennas with ground planes; GPS+BeiDou measured in Singapore
9
CEP, 50%, 24 hours static, -130 dBm, > 6 SVs
10
ppm limited to baselines up to 10 km
