The iREF-GNSS-BASIC is a RTK GPS reference station which comes in a highly ruggedized water-tight enclosure and provides an autonomous power provision, an advanced integrated GNSS engine, an integrated UHF or VHF radio modem or NTRIP interface for communication to an unlimited amount of rovers and several interfaces like RS232 and RS422.
The iREF-GNSS-BASIC is equipped with sturdy connectors and is designed for autonomous operation. Two high density hot-plugging batteries allow a long time operation including data transmission to mobile rovers via radio modem on VHF or UHF band or via NTRIP. An LTE GSM modem of type iNetGo+ can be connected to support even a fast initial position survey via RTK correction data which might be distributed by a local commercial provider (in this case these correction data are only used a very short time once to acquire the true position of the just installed GNSS antenna of the iREF).
The batteries of the iREF-GNSS-BASIC can be charged inside the iREF-GNSS-BASIC.
The iREF-GNSS-BASIC can be supplied by the internal batteries or via external provided 10...28 V DC or via 100...240 V AC power.
Options for data transmission are UHF 433 MHz or VHF 160 MHz band, or iMAR's iDMN Dynamic Mesh Communication Network or any other NTRIP capable network.
To survey the position of the iREF-GNSS-BASIC, correction data input obtained from TerraStar or AxioNet/SAPOS or similar or NTRIP is supported as an option.
The software iXCOM-CMD (under Windows and Linux) for the user's PC / laptop is included to configure the iREF and to perform a data download, e.g. to provide them for post-processing. It is the same software as also used to operate all iNAT, iTraceRT-MVT, iSULONA, iCOMBANA, iPRENA and iATTHEMO systems.
The iREF-GNSS-PRO is similar to the iREF-GNSS-BASIC, but it contains additionally the following features:
The iREF-M200 is a very small, light-weight and robust GNSS reference station, which 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). iDMN Dynamic Mesh Communication Network is supported, RTK correction data are provided via NTRIP.
Hint: Instead of the iDMN also any other IP based network can be connected via Ethernet to transmit the NTRIP data from the iREF-M200 to the rovers. The advantage of iMAR's iDMN Mesh Communication Network is very low latency and jitter.
The weight of iREF-M200 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) is included to configure the iREF-M200, the iREF-GNSS-BASIC and iREF-GNSS-PRO and the communication network iDMN.
