Comparison of Features
u-blox provides the following table comparing key high-level differences between the features on the ZED-F9P and the ZED-X20P:
We've also compiled the differences between the chips across more specific features:
| Parameter | ZED-F9P | ZED-X20P |
|---|---|---|
| PPS Accuracy | 30 ns | 20 ns |
| Convergence Time | < 10 s | < 7 s |
| Max Velocity | 500 m/s | 300 m/s |
| Velocity Accuracy | 0.05 m/s | 0.03 m/s |
| Backup Battery Current | 45 µA | 32 µA |
| SW Backup Current | 1400 µA (1.4 mA) | 93 µA |
| Peak Current | 130 mA | 80 mA* |
| Acquisition Current | 95 mA | 68 mA* |
| Tracking Current | 93 mA | 64 mA* |
Notes: u-blox has recently removed support for the GLONASS GNSS constellation. This is not accounted for in the listed current consumption of the ZED-X20P.
