VYTIS-AR
GALILEO HAS-ENABLED UNIVERSAL GNSS
RECEIVER
Vytis-AR is an universal high precision PPP (Galileo HAS enabled) / RTK GNSS-INS receiver with OSNMA authentication, providing centimeter-level position accuracy in PPP mode.
NT1058.AR
GNSS BASEBAND PROCESSOR
NT1058.AR is a computing system on a crystal, which include digital Baseband Processor, HAS signal demodulation IP block, IP cryptographic block for OSNMA implementation and 128-channels hardware correlator for tracking and primary processing of digital signals of Galileo (E1, E5b, E5a, E6, E5 AltBOC), GPS (L1, L2, L5), GLONASS (G1, G2), BeiDou (B1, B2) GNSS constellations.
NT1068.AR
RF Front-End IC
NT1068.AR is a four-channel RF Front-End IC for the reception of GNSS signals (GPS, GLONASS, Galileo, BeiDou, NavIC, QZSS) at all frequency bands in various combinations: S, L1, L2, L3, L5, E1, E5a, E5b, E6, B1, B2, B3.
GNSS correction services at decimeter and centimeter levels have been available for more than a decade and provided by the main GNSS augmentation service providers, and farmers subscribe to relatively expensive GNSS correction services tailored to each user. The introduction of High Accuracy free of charge Service (HAS) through the Galileo program is a breakthrough technological advance for current and new potential applications especially for small farms with a limited budget. Moreover, positioning solutions in GNSS receiver should combine the use of Galileo HAS with independent measurements derived PVT solutions from multi-frequencies Galileo, GPS, GLONASS, BeiDou constellations and from IMU sensors to achieve better accuracy, availability, sensitivity and robustness against interference and deliver a robust and enhanced positioning service.
To offer customers modern solutions for precision agriculture based on Galileo HAS according in accordance with actual market needs, NTLAB starts to implement EUSPA funded project “HAS enabled universal GNSS receiver for precision agriculture [Vytis-AR]”.
The aim of the project is to carry out research and design to consolidate a specific HAS service both through E6 and Network Transport of RTCM via Internet Protocol (NTRIP) with real-time processing and positioning computation for agriculture applications, to develop and test prototype products with unique characteristics, its assessment and performance validation in an operational scenario, to start the preparation of GNSS receiver for mass production and to validate performance of HAS service with feedback to EUSPA for the HAS full service consolidation.
The products are aimed at improving the efficiency of navigation receivers and the availability of high-precision navigation systems for agricultural applications.
The project is funded by the European Union Agency for the Space Programme (EUSPA).
