Up-to-date diminutive designed and manufactured in Russia GLONASS module NAVIA ML8088s used for detection the current coordinates and velocity of object in real time and off-line mode, to form second timestamp and exchanging with external devices via RS23
The operating principle of the receiver is based on parallel receiving and processing of signals from navigation GLONASS SC by 32 counting channels in frequency band L1 (CT or PT code), GPS on L1 frequency (C/A code) and GALILEO on E1 frequency. NT solution results are issued in NMEA messages format.
GLONASS module NAVIA ML8088s is the ideal solution for miniaturization and compactness. ML8088s navigation receiver is built on a state-of-the-art dedicated chipset STA8088F from the family of so-called “systems-on-a-chip” STA8088FG.
The receiver has high sensitivity, low power consumption and short cold/warm/hot start time.
The receiver is provided with two searching (capturing) channels and 32 channels for satellite signals tracking, which ensures simultaneous searching for satellite signals of GLONASS and GPS constellations.
The receiver makes it possible to use satellites almanac and ephemeris datas stored in the receiver memory for initial search of satellite signals; this ensures reduction of cold start time and, which is more important, makes it possible to perform the cold start when the signals from satellites are weak. The mentioned datas can be prepared by external sources (and transferred to the receiver via data links), as well as by the receiver itself. In the latter case, no additional information from the external sources is required.
The NAVIA ML8088s is provided with built-in 3-state jammer barrier feature, which allow the receiver to operate under high interference signaling environment.
