RTK GNSS
Real-Time Precision
Real-Time Kinematic provides centimeter accuracy instantly in the field.
Pros
- Instant results
- Field verification
- No post-processing
Cons
- Requires connection
- Base station needed
Best For
PPK GNSS
Post-Processed
Post-Processed Kinematic achieves RTK accuracy without real-time connection.
Pros
