NTRIP vs radio link for base-rover corrections - pros and cons
We're setting up a second survey crew and debating whether to go NTRIP-only or invest in UHF radios for the base-rover link. Currently our main crew uses NTRIP everywhere and it works fine in suburban and urban areas. But the new crew will be doing more rural work.
Here's my comparison after running both setups over the past year:
NTRIP (internet-based corrections):
- Pro: No extra hardware to haul, maintain, or charge
- Pro: Long baseline support (works 20-30km+ from the reference station)
- Pro: State networks mean you don't even need your own base
- Con: Requires cell coverage, which is the dealbreaker in rural areas
- Con: Monthly subscription cost ($150-300/mo for commercial networks)
- Con: Latency can spike if your cell connection is weak
UHF/LoRa radio link:
- Pro: Works anywhere with no internet dependency
- Pro: Very low latency, typically under 1 second
- Pro: No monthly costs after initial purchase
- Con: Line of sight limitations - hills and trees block the signal
- Con: Another piece of equipment to set up, power, and maintain
- Con: Baseline limited to 5-10km typically (less with obstructions)
- Con: FCC licensing required for some frequencies
For our situation I'm leaning toward equipping the new crew with both. NTRIP as primary where cell coverage exists, radio link as backup for the rural sites. Costs more upfront but they'll never be stuck without corrections.
Anyone running a dual setup like this? Curious how you handle the switching in the field.
