- Page 8 About MIRA Compact The MIRA Compact and the data acquisition software MIRA Controller are efficient and easy-to- use multi-channel systems for 3D GPR measurements. The MIRA Compact system enables measurement combinations between any of the individual receiver and transmitter antennas used in the array, and all antennas use the MALÅ HDR technology (High Dynamic Range).
- Page 9 Guideline Geo within fourteen (14) business days of receiving the equipment. Repacking and Shipping The Guideline Geo wooden freight crate is specially designed to ship the MIRA Compact. This crate should be used whenever shipping is necessary. If original packing materials are unavailable, pack the instrument in a large box to allow at least 80 mm of shock-absorbing material to be placed all around the instrument.
- Page 10 Overview MIRA Compact In short, the MIRA Compact system comprises the following parts: • MIRA Compact antenna box. A special antenna box for deploying the MIRA Compact system holds six receiver (Rx) and five transmitter (Tx) antennas with a central frequency of 500 MHz.
- Page 11 System Setup 1. Connect the Ethernet cable between the computer with the MIRA Controller installed and the connector marked Ethernet on the connector panel of the antenna box. See section Antenna box. 2. Make sure that the encoder cable is connected between the MIRA Compact carrier frame and the Encoder connector on the connector panel of the antenna box.
- Page 12 RTK GNSS. Any USB-C cable can be used; however, it is strongly recommended to use the supplied cable since it protects the connector on the antenna box. Spare cables can be purchased directly from Guideline Geo or your local MALÅ partner. The Ext. Antenna connector is intended for future features.
- Page 13 Built-in GNSS The MIRA Compact has a built-in GNSS module that utilises the Pulses Per Second (PPS) output to synchronise the recorded traces with the external RTK GNSS measurement input. This aids in an improved positioning and alignment of each recorded trace due to potential latency between the external GNSS and the MIRA Compact.
- Page 14 The batteries can also be charged in the external intelligent battery charger, where two batteries can be charged at the same time. Powering the MIRA Compact batteries with the external charger is done as follows. Powering the charger: 1. Connect all cables to the charger and plug it into the mains socket. 2.

- Page 19 Pivot wheel The carrier frame has a pivot wheel at the front for easy manoeuvring. This can be locked to a straight position using the lock pin. Pull the pin upward to release and rotate a quarter of a turn. To lock, ensure the wheel is straight, then rotate the pin a quarter of a turn, and it will slide into position to lock the wheel.
