Advanced RTK GNSS Reference Station

The iREF-M300 is a very small, light-weight and robust GNSS reference station to provide and distribute GNSS correction data (RTK, DGPS). iREF-M300 will be supplied by an external DC voltage (9...34 V DC, < 10 W); overvoltage and spike protection as well as EMI/EMC protection according to MIL standards is included. Ingress protection class is IP69 for all-weather operation. As as an option iREF-M300 will be provided as a dedicated setup for naval environment (for this please order the iREF-M300 with dedicated connectors).

The internal GNSS engine supports all-frequencies / all-constellations. The RTK accuracy is +/- 1 cm under sufficient GNSS conditions. Data rate is adjustable.

iDMN Dynamic Mesh Communication Network is supported, RTK correction data are provided via NTRIP. Also radio modem interface (e.g. for 130 MHz data transmission) is available.

Hint: Instead of the iDMN also any other IP based network can be connected via Ethernet to transmit the NTRIP / RTCM / RTCA data from the iREF-M300 to any destination (e.g to mobile rovers). The advantage of iMAR's iDMN Mesh Communication Network is very low latency and jitter.  

The weight of iREF-M300 is less than 850 grams. 

The Windows and LINUX based configu­ration software iXCOM-CMD (same software as used to operate the navgation systems of families iNAT, iTrcaeRT-MVT, iPRENA, iCOMBANA, iSULONA, iATTHEMO, etc.) is included to configure the iREF-M300 and - if desired - the communication network iDMN or an WiFi interface.
