LG290P on Linux

Figured out the QGNSS software and RTK so I thought I’d give it a shot on a Pi. Easiest route is by using pygpsclient.

I can only get an RTK Float because everything is indoors and it is a crummy rainy day. This is a heck of a lot more fun than I thought.

Cool! Have you written any tutorials on it? Please share if you have written any. Thanks.

I touched on it briefly in one of my blogs. There is a Heading labelled “Linux” down the page some.

PiOS setup for PyGPSClient

Thank you. I’d like to know one thing. Did you ever notice any change in the RTKs behaviour under cloudy sky?

My property is completely surround by a dense growth of trees. And yesterday was cloudy. I would go between RTK Fixed and RTK Float depending on the conditions.

Hi @JohnEH Good to see you’re having fun with PyGPSClient :+1:

FYI crummy weather and an indoor urban environment need not necessarily be a major impediment to good RTK performance. A good multiband antenna and a high quality NTRIP source can go a long way. Ideally you should have 10 or more satellites with cno > 45 dbHz for the best results.

Here’s an LG290P with a Beitian BT-184 mini choke ring antenna mounted in a inside loft space in Manchester UK (a city with mythically bad weather!) with a reasonably local EUREF/IGS NTRIP source (baseline 29km - not ideal but workable). Choke ring antennas, while more expensive than standard active patch antennas, are particularly well suited to areas prone to multipath distortion, such as urban or forested areas:

There is a fairly comprehensive tutorial here, but if you have any queries, don’t hesitate to post a question to the PyGPSClient discussion forum.

By the way - if you’re looking to install PyGPSClient on a Raspberry Pi or any other Debian or Arch based Linux platform, the quickest and easiest route is probably via these installation shell scripts.
