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. 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.
Why does the P-10 Pro or P-7 Pro get 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, whose accuracy values are converted from the HDOP values. The accuracy value of dual-frequency GNSS receivers (P-7 Pro, P-10 Pro) can not simply be converted this way, (The coordinate reading of those apps are accurate though. ) so please do not rely on those accuracy readings. 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.
The explanation of vertical accuracy of P-7 pro or P-10 Pro
Posted by jack wu on
According to the technical specs, the vertical accuracy of Columbus P-7 Pro or P-10 Pro GNSS is 15 meters. I was told by the Columbus engineer, the 15 meters vertical accuracy originates from the GPS chipset technical specs. In the real world tests, the average vertical accuracy is around 5 meters. Compared to the 50 meters vertical accuracy of most single frequency GPS/GNSS , the P-7 Pro or P-10 Pro still has great advantages.
