- Page 8 About MIRA Compact The MIRA Compact, together with the data acquisition software MIRA Controller is a very efficient and easy to use multi-channel system 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 are using the MALÅ...
- Page 9 Guideline Geo within fourteen (14) business days from the receipt of the equipment. Repacking and Shipping The Guideline Geo packing kit is specially designed for shipping MALÅ MIRA Compact. The packing kit should be used whenever shipping is necessary. If original packing materials are unavailable, pack the instrument in a box that is large enough to allow at least 80mm 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. Special antenna box for deployment of the MIRA Compact system, holding 6 receiver (Rx) and 5 transmitter (Tx) antennas with a central frequency of 500 MHz.
- Page 11 System set-up 1. Connect the Ethernet cable between the computer or tablet with MIRA Controller installed and the connector marked Ethernet on the connector panel of the antenna box. See section Antenna box. 2. Mount the GNSS antenna and if using a RS-232 cable for your GNSS, connect this to your computer.
- Page 12 System components Antenna box Antennas The MALÅ MIRA Compact antenna box is available with a centre frequency of 500 MHz. This frequency will cover investigations depths down to approximately 4 meters. The maximum measurement depth will vary and depends for example on the soil conductivity locally. The MIRA Compact antenna box houses 5 transmitters and 6 receivers.
- Page 13 Batteries The MIRA Compact is powered by four 14.4V Li-Ion batteries. The batteries are located in the battery compartment behind the two black lids. Make sure the lids are securely closed to prevent water and dust from entering. The batteries are hot-swappable, meaning that batteries can be exchanged while the system is running as long as at least one charged battery is kept in the system.
- Page 14 How often it needs to be replaced depends on how the system is used, including factors such as ground conditions. We recommend inspecting the skid plate before and after each use. New skid plates can be purchased directly from Guideline Geo or through your local MALÅ partner.
- Page 15 How to replace the MIRA Compact skid plate: 1. TBD Straps Carrier frame Antenna assembly The antenna is mounted in the carrier frame using four straps and two stabilizer arms. The floating antenna solution makes it possible to operate MIRA Compact over uneven surfaces. The ground clearance is easily adjusted using the straps.
- Page 16 Data acquisition software The MIRA Controller data acquisition software is used to collect, view, and save data from the MIRA Compact. The software is an easy to use and straight forward application, for more information, see the MIRA Controller User Guide. The computer or tablet used for measurements should be placed in a convenient position for the operator to monitor the measurement progress whilst carrying out the investigation.
- Page 17 Positioning The antenna array must be positioned with a high level of accuracy throughout the survey. A precise control of the geometry is an absolute prerequisite to make the resulting 3D radar picture correct and reliable. Centimetre accuracy is needed over the whole investigation site. The MIRA Compact can be positioned by using an RTK GNSS or Total station solution.
- Page 18 When a longer pole is needed, we highly recommend using the MALÅ GNSS support kit which includes a 800 mm pole. Note: The MALÅ GNSS support is only compatible with 25 mm diameter poles.
