I have spent most of the afternoon reading about RTK NTRIP and playing with SW Maps; I feel I have a reasonable understanding of how it works now.
I am a radio ham and have used a friend’s Emlid GPS unit in the past to measure out long lengths of wire (630m, 160m) for antenna projects and also where to put up poles for supports.
I’d like my own setup that is much more accurate than just my phone’s GPS in SW Maps to plan out antenna projects etc. From the reading I have done and for hobby use, I think the SparkFun postcard with NTRIP data and SW Maps will do what I want, but I wanted to ask the question to people more experienced with the product to see if there is anything I should be aware of before buying one.
No stranger to ESP32, Pi, and Arduino.
Thanks so much for taking the time to read the post.
Depending on how you plan to power the PostCard, you might want to also purchase the Portability Shield to easily recharge a Li-Po inside an enclosure, etc.
With the recent developments in HAS/E6 corrections on the LG290P, you also have a free correction source available that might fit your needs if cellular/NTRIP isn’t available to you.
Note: I’d personally pick a small helical antenna if using NTRIP (for convenience), or a larger “UFO” style for the free HAS/E6 corrections. I mention HAS/E6 because you probably aren’t looking for cm accuracy based on your post.
If/when you start looking for a “finished” form-factor, the TX2 is a solid choice, or the FPL, both have the same LG290P inside that the PostCard uses.
