Measure more dynamically.

By measuring and reporting our receiver's specific force, angular rate, and sometimes orientation via a combination of accelerometers, gyroscopes and magnetometer, Rimu Technology enables surveyor to measure dynamically with an estimated position and head if the receiver loses satellite connection or under a poor condition of satellite signals (e.g. near tunnels, buildings, etc). 

Rimu provides reliable and accurate tilt compensation for RTK, and surveyor can measure without alignment, and no longer needs to level the receiver before getting fixed. 

Easy Initializtion

5-8 seconds shaking left-right to get initialization.


<2cm within 30° tilt

<5cm within 60° tilt

Fast Re-activation

By moving 1-2 seconds, we can re-activate it on the next point.

Immune to Magnetic

Not affected by magnetic field nearby, such as powerline. 

Powerful Data Link

Up to 3W internal UHF. 

Easy to reach 6-8km. 

410-470MHz Dual Frequency

Supports protocols:

TrimTalk450s, TrimMark3, PCCEOT, SOUTH

Radio Router

When R90i links to a reference station with only one user ID, it gets differential corrections through the cellular network, then transmits the corrections to other rovers through internal UHF as a router.

Radio Repeater

When R90i links to a base station, it gets differential corrections through internal UHF, then transmits the corrections to other rovers through internal UHF as a repeater.


Power Scheme

The power supply system of R90i allows 2 batteries loaded with hot-swapping feature which ensures a non-stop operation.

PowerHub is a specifc power bank containing 4 batteries, which is able to hung on a tripod as an external power when R90i is working as a base station for a continuous operation. 

Worry about recharging so many batteries? QuadCharger provides you an ideal solution. You can recharge 4 batteries at one time which will be more than sufficient for one day's use for 2 receiver. 

Easy monitoring and setting via computer or phone.

WiFi Hotspot

Web Server

R90i is equipped with a WiFi module, which enables our computers and smartphones to connect to the receiver via hotspot. That means a lot, because we can log on RUIDE Web Server to monitor the working status and configure almost all settings of the receiver, anytime, anywhere, wirelessly.
