GEODNET vs RTKdata
Two low-cost RTKReal-time kinematic. A way to make GPS accurate to about an inch by getting live corrections from a nearby base station.Full definition services at the same list price. Here's what's actually different.
The short version
- Both list $40 a month per device. Both show $400 a year too, though GEODNET's yearly price comes from an earlier store listing.
- RTKdata also sells a 5-year plan for $1,920 and publishes a 30-day free trial with no credit card. GEODNET offers a free trial too (link on its store page).
- GEODNET is built from community-hosted Base stationA GNSS receiver sitting still on a known spot. It figures out how wrong the satellite signals are right now and shares that as corrections.Full definition. Its CorrectionsLive info from a base station about how far off the satellite signals are, so your rover can cancel out the error.Full definition work best within about 20 km of a station, so check its map for a station near your site.
- RTKdata says it uses 20,000+ stations in 140+ countries and gives you one Mount pointOne specific correction stream on a caster, like one channel on a radio. Each one comes from a certain station or network setup.Full definition (AUTO) that picks for you.
- The honest answer: whichever has a station closer to where you work wins. Check both maps for your exact site.
