Main Features of the UAB Snapshot GNSS Receiver
| Feature | UAB Snapshot GNSS Receiver | |
|---|---|---|
| Solution | Remark | |
| Operating system | Any supported by MATLAB | |
| Programming environment | MATLAB | MATLAB version 6.0 (R12, 2000) or higher. |
| Processing mode | Post-processing | |
| Supported GNSS | GPS (L1 C/A, L5), Galileo (E1C, E5a) | |
| Acquisition | FFT-based signal acquisition | Implementing the double-FFT algorithm for both code correlation and bit synchronization. Long correlations can be implemented by noncoherently combining a set of coherent correlations. A-GNSS is used to narrow the acquisition search space. Compatible with 3GPP RRLP-compliant XML data. |
| Tracking | None | No tracking is implemented because the receiver architecture is based on snapshot mode (i.e., acquisition-only). |
| Navigation | Weighted least squares | Coarse-time navigation is implemented. |
| Further features | Implements near–far detection and interference detection | |
