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…

For HAS/E6: Choke-Ring & “UFO” Antennas are performing much better than Helical & Patch/Puck Antennas. I guess that’s not unexpected. My Helicals and Pucks “can” produce accurate HAS/E6 positions, but they can also get it wrong fairly easily. Antenna selection appears to be much more critical …

Hi everyone. Last night I took measurements while changing antennas. What I’ve seen these past few days I verified again. With the Beitian BT-770, I get repeatable results within 30 cm (1 foot) and sometimes much better. For Galileo HA, we need a good antenna, and it seems to be quite consistent …

Hi Marco ( @bamarcant ) Could it be that you have a BT603 in your measurement experiments? If you confirm, please tell me how it generally works for you.

Sure, but I’m using a clone of the BT-603 since Beitian also has the BT602 I was afraid they would get confused and I chose Starf… I ran some more tests using the good BT-T076 and the recent STA-609 both helical (for convenience), here are the results: [immagine] [immagine]

[image] rftop: I think Marco ( @bamarcant ) made a great point in this thread. HAS/E6 could be useful during the survey-in procedure for a local Base/Rover. The FW could watch for PPP convergence (State 7 in the PPPNAV message), then cook for a few more minutes (user defined) before automatically …

I am glad you liked the video! A big thank you @bamarcant for the idea!

I figure this a good thread to report a recent test. TLDR: The Base Assist Mode is a NICE feature, and works well with a HAS/E6 corrected Base if you don’t have a NTRIP source available. I’m also impressed with the simplicity of using the ESP-NOW radios with Sparkfun RTK devices for local Base/Rov…

@sparky and @PaulZC , Quick discussion about Base Mode in the HAS/E6 context. I’m thinking about a “no-touch” PostCard Base for HAS/E6. Power it up, and it collects HAS for 30 minutes (survey-in) and then begins Base Operations. No buttons or config needed (after the initial setup). We are curr…

I did notice the Age of corrections on the Rover started to increase and become unstable when I had the Android Tablet (SPP/Bluetooth Classic) connected to the Base to make config changes during testing. That PostCard Base was sending Corrections to RTK2Go over WiFi while also serving a local rover…
