Who needs this?
Anyone staking property lines, setting control, running drone GCPs, or verifying machine guidance. Network RTK (NTRIP) removes the need for a local base when cellular coverage and VRS networks are available.
RTK vs PPK
- RTK: Corrections in real time — best for field work where you need immediate fixes.
- PPK: Raw data logged and corrected in the office — useful in remote areas or when radio/cellular links are unreliable.
What to look for on a spec sheet
- Multi-frequency
- L1/L2/L5 support improves tracking and ionospheric resilience.
- Tilt compensation
- IMU-assisted measurement without perfect rod verticality — huge for productivity.
- Data link
- Radio, cellular NTRIP, or satellite corrections — match your job site.
