The Septentrio PolaRx2e@ brings heading, attitude and other multi-antenna applications within economical and practical reach. It is the only compact single-board attitude receiver on the market. The attitude variant is available either as a standard Euro-card-size board, ensuring easy integration or packaged in a rugged enclosure for ready-to-use solutions. The PolaRx2e@ is offered in a strong and waterproof enclosure with sturdy connectors, allowing usage in tough and remote environments. It also offers new features such as logging control via push button or external signals and programmable LEDs. Finally, a new model, PolaRx2eH, is introduced, featuring 2 dual-frequency antenna inputs. The PolaRx2eH is ideally suited for machine control applications and similar challenging dual-antenna/heading applications.
48 channels can be flexibly assigned to track satellites in single or dual frequency on one, two or three antennas in parallel. One or more antennas can also be used to track SBAS augmentation satellites. It brings precise heading, pitch and roll as well as accurate position and velocity at update rates of up to 10Hz. Raw data can be output for all antennas. An optional module, PLRX_ATT, is available to calculate and output the attitude angles from these measurements. It can be implemented by simple software.
The main antenna is in principle dual-frequency while the auxiliary antennas are single frequency. However, an all single-frequency version is also available in case only heading information and no precise position information is required.
Septentrio has developed a flexible FPGA extension platform to the existing PolaRx2 receiver, PolaRx2C, capable of receiving the coming L2C signals, that are part of the GPS modernisation. An important objective of GPS modernisation is to preserve civil use. The first stage in the GPS modernisation process has started in 2005, with the launch of the first satellite that will transmit civilian signals on the L2 band, called L2C signals. The L2C signals consist out of 2 PRN codes: the CM code and the CL code.
The PolaRx2C architecture results in a very low tracking noise. The design supports active multi-path mitigation, using both CM and CL and features modularity. The advantage of a combined platform, PolaRx2C, is that next to research on the first L2C signals, a complete dual-frequency P(Y) code receiver is offered. The L2C extension has the same high quality measurements (low noise, high sensitivity) as the standard PolaRx2 receiver
The Septentrio PolaRx2e_SBAS receiver can track the L1 signals from up to 6 SBAS augmentation satellites such as EGNOS and WAAS. This offers your application vital integrity information, increasing the confidence in the positioning solution and allowing application in safety-critical environments. The receiver may also be used either as base station or as rover receiver for differential GPS and RTK. When the SBAS option is installed on the single-antenna version of the PolaRx2e, it will track SBAS satellites by default and will use the SBAS corrections in the optimal way. For the multi-antenna version, SBAS has to be configured manually.
The Septentrio PolaRx2e is a versatile 48-channel dual-frequency GNSS receiver for precise positioning, navigation and timing applications, requiring single-board integrated GNSS-based devices. It supports reception of the L1 and L2 signals from up to 16 GPS satellites. The PolaRx2e can be ordered as a standard Euro-card-size board or enclosed in a rugged housing. When ordered in enclosure, the receiver comes with 220V power adaptor, power cord, null modem cable and general purpose cable.
The PolaRx2e is designed for tough and remote field conditions and comes in an enclosure with sturdy waterproof connectors. It offers additional features such as logging control via push button or external signals, extra interface options and programmable LEDs.
A single-frequency model of the standard dual-frequency PolaRx2e receiver is available: the PolaRx2e_SBAS. The receiver can be used either as base station or as rover receiver for differential GPS and RTK.
The Septentrio PolaRx2eH heading receiver is the latest variant in the PolaRx2 family. The PolaRx2eH can be connected to 2 dual-frequency antennas to output accurate heading & pitch or heading & roll information. For ready-to-use solutions, the receiver comes in a waterproof IP65 enclosure with sturdy connectors, allowing usage in tough and remote environments. This variant is available as a standard Euro-card board, ensuring easy integration.
The enclosed receiver offers 4 serial ports, a possibility of 256MB non-removable Compact Flash memory card and Ethernet access. New features include logging control via push button or external signals and programmable LEDs.
The lightweight and compact design of the PolaRx2eH bring important improvements to traditional GNSS-based heading applications whilst conjunctively opening the door for new application types.
MGB-Tech's RTK-GPS solution is based on Septentrio's AsteRx2e platform. It is build to be a one box solution. It incorporates a UHF radio, lithium-polymer battery and charger. The radio is programmable over a wide frequency range (406-470 MHz). It also has a wide input DC power supply (10-30 VDC). The four RS-232 ports are implemented with standard D-sub connectors for easy use.
