Instant-RTK® Initialization
• Independent of GPS availability when other GNSS signals
are available

• Typically 2-second initialization for baselines < 20 km
• 99.9% reliability
1.Each GNSS constellation is processed equally, individually and combined for optimal performance.
2.Accuracy and TTFF specifications may be affected by atmospheric conditions, signal multipath, satellite
geometry and corrections availability and quality. Position accuracy specifications are for horizontal
positioning. Vertical error is typically less than twice the horizontal error.
3.Performance values assume minimum of five satellites, following the procedures recommended in the
product manual. High multipath areas, high PDOP values and periods of severe atmospheric conditions may
degrade performance.
4.Each GNSS constellation is processed equally, individually and combined for optimal performance.
