GPS Receiver Modules GT-8031
Integrity is further improved because of its SBAS (WAAS) capability in addition to traditional T-RAIM (Time-Receiver Autonomous Integrity Monitor) function. Several new command sets have been added for easier use.
PPS output mode is available. For example, in "always output mode", 1PPS is output without satellite signals using the receiver's internal timing (no UTC synchronization). In "fixed observation point mode", one satellite signal is enough to output UTC synchronized 1PPS. application is infinite.
Characteristics
- Low cost but powerful, fast 16 Channel GPS receiver
- Accuracy is not sacrificed 15 nanoseconds with regard to UTC (1 sigma).
- Low power consumption (58mA@3.3VDC) at full tracking satellites
- RF pig tail cable with popular connector already soldered for easier, more cost-effective installation.
- Almanac uploading and downloading.
- Autonomous transition from "Survey" to "Fixed Observation Point" lets the receiver calculate its position and then use the averaged position as the fixed observation point.
- "Back to fixed position set" allows you to go back to the fixed position even after power-off.
