120 Channels

* "EPS Ultra" is Columbus' proprietary technology.

GNSS Performance

Upper L-Band (L1): GPS (L1C/A, 1575.42 MHz), Galileo (E1B/C, 1575.42 MHz), BeiDou (B1I, B1C, B1Q, 1561.098 MHz), GLONASS (L1OF, 1602 MHz), QZSS (L1C/A, L1S, 1575.42 MHz), SBAS (L1C/A)

Lower L-Band (L5): GPS (L5, 1176.45 MHz), Galileo (E5a, 1176.45 MHz; E5b, 1207MHz), BeiDou (B2a, 1176.45 MHz), QZSS (L5, 1176.45 MHz), IRNSS (L5, 1176.45 MHz)

Positioning Accuracy

RTK Mode:
Horizontal accuracy: 1.0 cm + 1 ppm* (Circular Error Probability / CEP 50%)
Vertical accuracy: 1.5 cm + 1 ppm* (Median)
Velocity accuracy: 0.05m/s
Dynamic heading accuracy: 0.3 deg

SBAS Mode:
Horizontal accuracy: 30 cm (Circular Error Probability / CEP 50%)

* Measurements are taken using a 1 km baseline. ppm is limited to a maximum baseline range of 20 kilometers. For every additional kilometer between the rover and the fixed station, the error increases by 1 mm. Testing is conducted in areas with a clear sky view.

* Based on a 1-hour static test.

Measurable Range

Maximum altitude: 80,000 m
Maximum horizontal speed: 1,800 km/h
Maximum vertical speed: 72,000 km/h
