Some quick testing of HAS/E6 with RTK Everywhere V3.1 on the PostCard : Initial PPP convergence took about 15 minutes in open sky. SW Maps reports RTK Float, which is expected since the GGA sentence reports Fix Mode 5 (RTK Float / PPP) when only using HAS PPP corrections. The same for the PVT me…

@rftop Thank you for your replies. Your comments were very thorough. But the latest beta version is LG290P03AANR01A06S_PPP_TEMP1107, and I’d like you to try it and compare it. Will you be able to? I agree that the ultimate goal of all this is to use Galileo HAS corrections in real time. I think…

The debug version was sent to me by email (Quectel) due to my comments about data loss and, of course, convergence issues at certain times of day in my area (Uruguay). I didn’t have time to test it, but I understand it was the same version 2.01 with added debug features. I then emailed it to Sparlky…

The algorithm used in 2.1 is more conservative… …HAS converges after switching from dgps(2) to rtk_float(5) in about 11 minutes after a disturbance or rtcm/ntrip correction,all the previous detected points enters at most within 30 cm . [immagine] However, with a good helical antenna I did not no…

Hi everyone Hi Marco ( @bamarcant ) Your contributions are great. I’m still seeing a significant correlation between ionospheric activity (you sent me some maps) and my connection problems and loss of good solutions. These days, ionospheric activity is lower in my area, and with the beta version, …

In order to remove any human bias: I’m performing blind tests in real-time: Place antenna in an Unknown location (no known coordinates) Reset the LG290P and let HAS/E6 perform it’s PPP convergence. Since I don’t know the actual position, I have to decide when I trust the HAS solution based on ONLY…

Below are the Blind Results after turning on ALL Frequencies and Birds. Each location started with a new & unknown position. Horizontal deltas of HAS/E6 (30 minutes PPP convergence) verses PointPerfect RTCM RTK (in cm): 4.5, 21.5, 16.9, 10.5, 4.0, 9.4, 3.6, 3.6, 15.9, 17.8 :chart_increasing: S…

Hi @rftop I have a question. I have the Postcard and I don’t know if the script modifications will be retained after a reboot. My question is whether the Sparkfun firmware will change those modifications. Last night I made the changes and the results seemed very good. Now, at midday in my count…

Today I tested a single HAS/PPP Convergence (as typical field work would). I used a 2-meter Rod with bipod and a geodetic choke ring antenna. All HAS points were collected with 30 epochs averaged in SW Maps. Then PointPerfect Flex (RTCM NTRIP) RTK points were collected for comparison. I did not …

HAS/E6 results on PostCard FW V3.1 with LG290P FW V2.01 [Feb 2026]

GPS/GNSS

I’m getting really good HAS/E6 results today with 20-30 minutes of initial convergence.
Repeatability (after dumping antenna) appears to have improved with the FW hacks.
