There are a few reasons why this might be the case. First of all, there aren't many SBAS satellites in the sky. Additionally, SBAS satellites are geosynchronous orbit satellites, which means they don't move across the sky like other satellites do. If the elevation angle of an SBAS satellite is too low, the P-7 Pro's GNSS chip (Broadcom chip) will determine that it's unhealthy and won't capture its signal. This is why you might not always see any SBAS satellites even when you've enabled them.During my tests of the P-7 Pro in the Toronto, Canada area, I found that I...

To reduce the unnecessary interference by static drift,  P-7 Pro enabled the static drift filter  by default. When the device is stationary, it filters the positions drift which are greater than or equal to 1.5 meters. If you want to disable or re-enable this filter, please follow the below step by step instruction. 1. If you didn't do so, please download the Windows USB driver of P-7 Pro from here. Install the driver.   2. Download GnssToolKit3 software from here , extract it and double click the GnssToolkit.exe.   3. Select the baud rate 57600.   4. Plug in the P-7 Pro to...

P-10 Pro can provide horizontal accuracy 0.5m/CEP(50%) and 1.5m/CEP(95%).  CEP refers to Circular Error Probable. 0.5m/CEP(50%) means that the probability of the track points falling within a 0.5m radius is greater than 50%; 1.5m/CEP(95%) means that the probability of the track points falling within a 1.5m radius is greater than 95% . In “static” scenarios, to acquire 0.5m/CEP (50%) accuracy, please follow the below prerequisites: Put the device in an open environment: no trees above, no tall buildings around. “Placement” and “time convergence” are the key factors to obtaining an accurate reading. Place the antenna receiving surface (front) of the...

"5 shorts beeps" indicates the file format error. The reason could be the "CONFIG.TXT" file you used to config P-10 has the wrong format.  This issue usually is because it is missing the 2 last characters, a CR and LF at  the end of the  CONFIG.TXT. Adding an "enter" at the end of the file will fix the issue. Please refer to the below screenshot.

1. If you didn't do so, please download the Windows USB driver of P-7 Pro from here. Install the driver.   2. Download GnssToolKit3 software from here , extract it and double click the GnssToolkit.exe.   3. Select the baud rate 57600.   4. Plug in the P-7 Pro to the computer's USB port.   5. Open the "Device Manager" from the Windows. Select Ports (COM & LPT). Note down one of the com ports number which showing "Silicon Labs Dual CP2105 USB to UART Bridge: Enhanced COM Port". I will use "COM10" in this instruction.   6. Connect the...
