The most detailed explanation of P-10 Pro accuracy.

Posted by jack wu on

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...

Why do I hear 5 short beeps (instead of 1 long beep) at the end of configuring P-10 Pro?

Posted by jack wu on

"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.  To fix this issue, you could down, unzip this file, then copy the "CONFIG.TXT" file to the root directory of the MicroSD card and process the config. You could change the parameters in "CONFIG.TXT" file if needed.

Posted by jack wu on

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...

Why does the P-10 Pro or P-7 Pro get dramatically less accuracy reading when testing by some apps?

Posted by jack wu on

The accuracy calculated by many apps in the market is based on a single frequency satellite system, so please do not rely on those accuracy readings. Instead, please observe the DOP values. For example, horizontal accuracy, you could refer to the HDOP value. Let's use P-7 Pro or P-10 Pro as an example: HDOP=1.0, the accuracy is 0.5m / CEP50%, HDOP=2.0, the accuracy is 1.0m / CEP 50%, etc. To properly test the accuracy of P-7 Pro, please follow the below "Columbus" official instruction. This instruction apply to P-10 Pro as well. https://cbgps.com/p7/app/gnsstoolkit/cep/index_en.htm

Why can't you see the constellations and number of satellites when using the P-10 Pro as a USB GNSS receiver?

Posted by jack wu on

The current firmware (V2.2) of the P-10 Pro does not open the GSV and GSA sentences, but only the GGA and RMC sentences. So it doesn't contain any information about constellations and individual satellites, that's the reason why you can't see the constellations and number of satellites within the GnssToolKit software or other testing tools.
