How do I best place the UNI-GR1 when I’m in the field?

Not regular GPS

In order to obtain the best results with the UNI-GR1 and any GNSS Receiver, it is important to place the UNI-GR1 in the right location. Many users may be used to standard GNSS receivers, or “location services” which work on tablets, mobile phones or other products and are used to having a “GPS signal” indoors. Unfortunately, this usually is a location based on your Wi-Fi or other services and not based on GPS, or that only a poor signal is received, generating an inaccurate position.

Get centimetre accuracy

When it comes to professional GNSS receivers like the UNI-GR1 with CM accuracy, it’s important to use other standards when placing the device. The UNI-GR1 is designed to eliminate many disturbing obstacles, however for optimal results take note of the following: To start, place the UNI-GR1 in a location where it has a clear line of sight to the sky at an angle starting at about 15-30 degrees and up. Do not place the UNI-GR1 near obstacles such as high buildings, vehicles and large trees or towers, to prevent any disturbance of the GNSS signals. It is recommended to place the UNI-GR1 on a survey pole for surveying or tripod for base set-ups (see Figures 1 & 2).
