- djsumdog 10y agoThose are also $3k ~ $5k and have to be configured to use a GPS base station. A professor once let us borrowed his. It had a full backpack and was supposedly accurate to 3cm using the airport as our base station.
- extrapickles 10y agoDGPS is much cheaper than it used to be as it is a feature of most GPS chipsets, though its poorly documented how you enable it. You also need to provide a serial data link between the two GPS units (for most applications this is over RF). Also, from my understanding, you only know the relative position of the two stations accurately, not the absolute world location.
- ghaff 10y agoYes but I'm not sure why that's relevant to most autonomous vehicles or typical commercial/consumer GPS use.
