Positioning performance

Precision and reliability may be subject to anomalies due to multipath, obstructions, satellite geometry, and atmospheric conditions. The specifications stated recommend the use of stable mounts in an open sky view, EMI and multipath clean environment, optimal GNSS constellation configurations, along with the use of survey practices that are generally accepted for performing the highest-order surveys for the applicable application including occupation times appropriate for baseline length. Baselines longer than 30 km require precise ephemeris and occupations up to 24 hours may be required to achieve the high precision static specification.

Code differential GNSS positioning

Horizontal

+/-0.25 m + 1 ppm RMS

Vertical

+/-0.25 m + 1 ppm RMS

SBAS differential

typically <5 m 3DRMS

SBAS differential performance depends on WAAS/EGNOS system performance.

Static GNSS surveying

High Precision Static

Horizontal

+/-3 mm + 0.1 ppm RMS

Vertical

+/-3.5 mm + 0.4 ppm RMS

Static and Fast Static

Horizontal

+/-3 mm + 0.5 ppm RMS

Vertical

+/-5 mm + 0.5 ppm RMS

Real Time Kinematic surveying

Single Baseline <30 km

Horizontal

+/-8 mm + 1 ppm RMS

Vertical

+/-15 mm + 1 ppm RMS

Network RTK

Horizontal

+/-8 mm + 0.5 ppm RMS

Vertical

+/-15 mm + 0.5 ppm RMS

RTK start-up time for specified precisions

2 to 8 seconds

Network RTK PPM values are referenced to the closest physical base station. RTK precision times may be affected by atmospheric conditions, signal multipath, obstructions and satellite geometry. Positioning reliability is continuously monitored to ensure highest quality.

Trimble RTX (Satellite and Cellular/Internet (IP))

CenterPoint RTX

Horizontal

4 cm

Vertical

9 cm

RTX convergence time for specified precisions

< 30 minutes (typical)

RTX QuickStart convergence time for specified precisions

< 5 minutes (typical)

Receiver convergence time varies based on GNSS constellation health, level of multipath, and proximity to obstructions such as large trees and buildings. Convergences times decrease significantly when using a “RTX Quickstart” on a previously surveyed point or a known survey control point.

Trimble xFill

Horizontal

RTK + 10 mm/minute RMS

Vertical

RTK + 20 mm/minute RMS

Precisions are dependent on GNSS satellite availability. xFill positioning without an RTX subscription ends after 5 minutes of radio downtime. xFill positioning with an RTX subscription will continue beyond 5 minutes providing RTX has converged, with typical precisions not exceeding 6 cm horizontal, 14 cm vertical. xFill is not available in all regions, check with your local sales representative for more information. RTK refers to the last reported precision before the correction source was lost and xFill started.
