(1) Multi-GNSS Support (GPS,GLONASS,Galileo and QZSS)
(2) Both of Offline and Real-Time Estimator
(3) PPP and PPP-AR
(4) Apply various L6E data formats (e.g. ubx/sbf/msj)
(5) Select frequencies depending on the GNSS satellites
♣ Signals of each supported satellite system
| Satellite system | Dual-frequency signals |
|---|
| GPS | L1C/A-L2P,L1C/A-L2C,L1C/A-L2P,L1C/A-L5 |
| QZSS | L1C/A-L2C,L1C-L5 |
| Galileo | E1-E5a,E1-E5b |
| GLONASS | G1-G2 |
♣ System Requirement
The CUI APs were also built and tested on Ubuntu 20.04 Linux and x86 CPU.
