DATASHEETTrimble R12i GNSS SYSTEM

1 Challenging GNSS environments are locations where the receiver has sufficient satellite availability to achieve
minimum accuracy requirements, but where the signal may be partly obstructed by and/or reflected off of trees,buildings, and other objects. Actual results may vary based on user’s geographic location and atmospheric activity,
scintillation levels, GNSS constellation health and availability, and level of multipath and signal occlusion.
2 The current capability in the receivers is based on publicly available information. As such, Trimble cannot guaranteethat these receivers will be fully compatible with a future generation of Galileo satellites or signals.
3 Precision and reliability may be subject to anomalies due to multipath, obstructions, satellite geometry, andatmospheric conditions. The specifications stated recommend the use of stable mounts in an open sky view, EMI andmultipath clean environment, optimal GNSS constellation configurations, along with the use of survey practices thatare 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.
4 Network RTK PPM values are referenced to the closest physical base station.
5 May be affected by atmospheric conditions, signal multipath, obstructions and satellite geometry. Initialization
reliability is continuously monitored to ensure highest quality.
6 TIP references the overall positioning error estimate at the tip of the surveying pole throughout the tilt compensation
range. RTK refers to the estimated horizontal precision of the underlying GNSS position, which is dependent on
factors that affect GNSS solution quality. The 5 mm constant error component accounts for residual misalignment
between the vertical axes of the receiver and the built-in Inertial Measurement Unit (IMU) after factory calibration,
assuming the receiver is mounted on a standard 2 m carbon fiber range pole which is properly calibrated and freefrom physical defects. The tilt-dependent error component is a function of the quality of the computed tilt azimuth,which is assumed here to be aligned using optimal GNSS conditions.
7 RMS performance based on repeatable in field measurements. Achievable accuracy and initialization time mayvary based on type and capability of receiver and antenna, user’s geographic location and atmospheric activity,
scintillation levels, GNSS constellation health and availability and level of multipath including obstructions such aslarge trees and buildings.
8 Accuracies are dependent on GNSS satellite availability. xFill positioning without an xFill Premium subscription
ends after 5 minutes of radio downtime. xFill Premium will continue beyond 5 minutes providing the solution has
converged, with typical precisions not exceeding 3 cm horizontal, 7 cm vertical. xFill is not available in all regions,check with your local sales representative for more information.
9 RTK refers to the last reported precision before the correction source was lost and xFill started.
10 Depends on SBAS system performance.
11 Receiver will operate normally to –40 °C, internal batteries are rated from –20 °C to +60 °C (ambient +50 °C).
12 Tracking GPS, GLONASS and SBAS satellites.
13 Varies with temperature and wireless data rate. When using a receiver and internal radio in the transmit mode, it isrecommended that an external 6 Ah or higher battery is used.
14 Varies with terrain and operating conditions.
15 Due to local regulations, the integrated cellular modem cannot be enabled in China, Taiwan, or Brazil. A Trimble
controller integrated cellular modem or external cellular modem can be used to obtain GNSS corrections via an IP(Internet Protocol) connection.
16 Bluetooth type approvals are country specific.
