Is it fair to say the GPS on board the Seeeduino LoRaWAN w/GPS has low accuracy?
We’ve been collecting location data on a few units and have found that:
- the HDOP looks suspect (starts at 0, sometimes just increments, bounces around a bit)
- the altitude varies by 10’s of metres
- the location moves around a area with a radius of about 80m with a stationary device, even when HDOP is <5.
I think maybe it’s handy to have a GPS on board to get the time and rough location, but it’s not much use for sub-10m use.
We’ll be evaluating the Grove GPS next. I hope the SIM28 performs better!
