1 Introduction
What is the R1 GNSSreceiver
The R1 GNSSreceiver is a high-performance GNSS receiver with an integrated antenna, and
Bluetooth® wireless technology for connectivity with field computers and smart phones. It is rated
IP65, and is small enough to be carried in a pocket or worn on a belt clip in its pouch.
The R1 GNSSreceiver achieves best real time performance when used with a real-time correction
source, such as SBAS, over L-Band (Trimble RTX™ technology), or IP via a phone device (Trimble
VRS™ or RTX technology).
Supported devices
The R1 GNSSreceiver is compatible with devices powered by the following operating systems:
l Android versions 4.1x and later l Windows® 7 and Windows 8.x
l iOS l Windows Embedded Handheld 6.5
Supported constellations
The R1 GNSSreceiver supports the following L1 constellations:
l GPS L1 C/A l BeiDou B1
l GLONASSL1 C/A (G1) l QZSS L1 C/A
l Galileo E1
Supported correction sources
The R1 GNSSreceiver supports the following correction signals:
l SBAS (WAAAS / EGNOS / MSAS / GAGAN, SDCM) l QZSS L1 SAIF
l CMR, CMR+, CMRx l RTX ViewPoint™ (via Internet and
L-Band satellite)
l RTCM 2.0 to 2.3 (DGPS and RTK), RTCM 3.0 and 3.1
CAUTION – SBAS and L-Band signals are highly compromised when the receiver is used close to the body;
geostationary satellites will have a lower signal margin at the receiver than the typical orbiting GNSS satellites.
Performance will heavily depend on factors such as user orientation, position of the receiver on body, how
exposed the antenna is, and geographic location.
