Setup compliance verification:
Before starting the gpsd APIs, the Antenna setup and GNSS firmware must be done.
• Antenna compliance:
— All the GNSS applications’ performance is expected to get good quality of antenna signal so the
software APIs can run on top of stable NMEA sentences.
— Table 8 shows the Antenna frequency band for ZED-F9T-00B. You should follow the original
vendor specification including supported band and circular polarization (the ZED-F9T-00B uses
right-hand circular polarization or RHCP).

• Leverage GPSD APIs to improve the E810-CQDA2T with the optional GNSS accuracy:
— gpsctl
• gpsctl can switch a dual-mode GPS between NMEA and vendor-binary modes. The gpsctl
API needs the gosd.socket service daemon running. Following is a basic device identification
example. You can use gpsctl -help to get all command details.
• With proper GPSD installation, the gpsctl can export terminal interface, as follows:
# gpsctl /dev/gnss0
where /dev/gnss0 is identified as a u-Blox SW EXT CORE 1.00 (3fda8e), HW 00190000 at
9600 baud.
