Hi,
I really like the idea behind the Propeller Aeropoints. Those are basically GCP targets with integrated PPK GPS. They are quite expensive, about $6.000 USD for 10 pieces, but that's still cheaper than a professional surveyor-grade RTK system, and probably more convenient for UAV mapping purposes.
However, I was wondering if a DIY version is possible and pays off?
In the end it's just a PPK receiver with power supply sitting in a rugged plastic plate... can't be that expensive...?

Hi,
Not far from the solution described by Tom, I build my own logger with a Raspberry Pi zero running RTKLib.
The GPS is a Ublox M8T.
Recently I added an oled screen.
Beside the survey with this "rover", I record GPS raw datas with the RTKBase, with another GPS, Raspberry Pi and RTKlib.
Hey Phil,
the cheapest solution would be to get a m8n gps from ebay or china and add a serial logger (openlog). This is known and used. Read up on this.
BOM:
ublox M8N or M8T
serial logger
power source (i used a "18650 cell" with a cheap charger from ebay "TP 4056")
2 switches (1 to turn on gps and get a good signal and 1 for the logger to start recording)
waterproof housing for e.g. electro installation
totals less than 100,--
another source for good information is rtklibexplorer wished this blag was available when i started with this...
i recently tried to a a esp8266 module and use it as serial bridge to check if the link quality is working fine.
Hey Philipp,
I'm also interested in finding an inexpensive way to increase the quality of our drone data. To that end... I found this link for an open source RTK system which looks promising. I'd be curious to find out if anyone else has found a cheap open source solution for RTK or PPK tools?
