INTRODUCING THE
TRIMBLE R1 GNSS RECEIVER
Workplace Trends - BYOD
Bring Your Own Devices (BYOD)
▪ Company owned devices
▪ Employee owned devices
▪ Company owned devices, issued to
individual employees
BYOD Positioning Constraints
▪ Assisted GPS (A-GPS)
– ~ 5-8 m
▪ Wi-Fi Positioning
– ~ 74 m
▪ Cellular Network
Positioning
– ~ 600 m
*** Not enough for professional applications ***
Zandbergen, P. A.” Accuracy of iPhone locations: A comparison of Assisted GPS, Wifi and cellular positioning.” Transactions in GIS, 13, 5–25
Small, Lightweight, Rugged
▪ Small
– Fits in vest or pocket
– 11.2 x 6.8 x 2.6 cm
(4.4 x 2.7 x 1 in)
▪ Lightweight
– 187 g (0.4 lb)
▪ Rugged
– MIL-810 Spec
– Real-world drop/impact
protection
– Battery
– 10hrs +
GNSS Receiver
▪ L1/G1
– GPS, GLONASS, Galileo,
Beidou, QZSS
– 44-channels, parallel tracking
▪ Higher accuracy
– Autonomous positioning
– Augmentation
– Corrections
Android / IOS Utility for Trimble R1
▪ GNSS Status utility
– Detailed status
▪ Receiver status
– App settings
▪ Unit system (Metric/US)
– Receiver options
▪ RTX subscription
– Real-time configuration
▪ Correction source(s)
*** Enables 3rd Party Applications ***

Windows 7 / 8 OS
Types of Corrections
Augmentation (SBAS)
▪ WAAS, EGNOS,
MSAS, GAGAN
▪ 4-channel, parallel
tracking
▪ Sub-meter accuracy
Virtual Reference Station (VRS)
▪ Networked Transport of
RTCM via Internet Protocol
▪ CMR, CMR+, CMRx
▪ RTCM 2.0, 2.3, 3.0, 3.1
▪ Sub-meter accuracy
HOW VRS NOW WORKS
Reference stations
continuously transmit
GNSS information to the
VRS central server
Position
Power your receiver and
cell modem and connect
to the VRS Network
RTX technology a different approach
Absolute positioning
ITRF2008
Modeling errors instead of
mitigating them by differencing
• Satellite orbit
• Satellite clock
• Atmospheric effects
GPS / GLONASS / BEIDOU/
QZSS
