The short version
- KeyNetGPS publishes its prices: $375 for 30 days, $3,135 a year prepaid, or $275 a month on a yearly plan.
- SmartNet doesn't publish US prices. You have to ask for a quote.
- KeyNetGPS covers 12 Northeast states plus DC, from Virginia to Maine, on a Trimble VRSVirtual reference station. The network blends nearby stations to create a pretend base right next to you, which keeps the baseline short.Full definition network.
- SmartNet says it covers all 50 states with 1,500+ stations, but doesn't publish a state list.
- If you work only in the Northeast and want a known price, KeyNetGPS is easy to budget. If you work across regions, get a SmartNet quote to compare.
