Table 2 Noise variance settings for the orbit parameters
From: A review of real-time multi-GNSS precise orbit determination based on the filter method
Strategy | Noise variance | ||
|---|---|---|---|
Satellite positions (m) | Satellite velocities (m/s) | Solar radiation pressure parameters (nm/s2) | |
Reference | \(1.0 \times 10^{ - 8}\) | \(1.0 \times 10^{ - 8}\) | \(1.0 \times 10^{ - 8}\) |
Weak constraints | \(1.0 \times 10^{ - 5}\) | \(1.0 \times 10^{ - 5}\) | \(1.0 \times 10^{ - 5}\) |
Strong constraints | \(1.0 \times 10^{ - 11}\) | \(1.0 \times 10^{ - 11}\) | \(1.0 \times 10^{ - 11}\) |
