GPS, WAAS, EGNOS and Beacon
The Seres is a smart GPS,WAAS, and EGNOS receiver and antenna solution in a single compact, convenient enclosure. It is designed for a variety of applications including Precision Agriculture, GIS, and Mapping.

High Performance GPS
The Seres uses a new GPS engine architecture that provides faster startup and acquisition times. With a current almanac and ephemeris, the SERES will provide a position within 35 seconds. If it’s been powered within the last couple hours, the Seres will provide a position within approximately 20 seconds.
Unlike many other smart antenna products, the Seres delivers high accuracy, and high position update rates with low power consumption.

SBAS Support
The US Federal Aviation Administration’s Wide Area Augmentation System (WAAS) is now undergoing rigorous final testing for its Initial Operation Capability.

Other WAAS compatible space-based augmentation systems are also under development, such as the European Geostationary Navigation Overlay System (EGNOS) and the Japanese MTSAT Satellite-based Augmentation System (MSAS), among others. The Seres provides compatibility for each of these free GPS augmentations.

Interface
The Seres features a combination power/data cable that is available in a variety of terminations to suit your needs. The cable interface provides power input to the antenna and features dual serial ports, an event marker input, 1 PPS output, and signal outputs intended for illuminating remote status LED indicators.

COAST™ Technology
COASTTM technology allows the Seres to use old correction data for up to 30 minutes or more without seriously affecting the quality of your positioning. Using COASTTM, the Seres is less likely to be affected by differential outages due to differential signal blockages, weak signal, or interference. No other product offers this flexibility.

Monitoring Software
CSI Wireless freely distributes SLXMon, a Windows-based software used to configure and monitor the operation of the Seres smart antenna. This program is available for free public download from CSI Wireless’ Satloc subsidiary website: www.satloc.com.

GPS Compass
The Vector ST and Vector Pro GPS compasses are designed to provide your marine navigation system with reliable, accurate heading and position information.

Inside the Vector ST & Pro, two GPS engines work cooperatively, resolving extremely accurate heading with a sophisticated moving base station Real-time Kinematic (RTK) solution.

The Vector ST offers 1 Hz heading and position updates with a heading accuracy of 1.0°. The Vector Pro offers higher performance with a heading accuracy of 0.5°degrees, and heading and position update rates of up to 5 Hz.

Both versions provide sub-metre DGPS positioning when using free correction data supplied from internal WAAS, EGNOS, demodulators.

SBAS
The American Federal Aviation Administration is currently testing its Wide Area Augmentation System (WAAS) in preparation for Initial Operational Capability. This service provides accurate, reliable GPS correction data throughout much of North America.

WAAS-compatible Space Based Augmentation Systems (SBAS) are also under development throughout the world, including the European Geostationary Navigation Overlay System (EGNOS) and the Japanese MTSAT Satellite-based Augmentation System (MSAS). The VECTOR ST & PRO receive these free correction services with their built-in SBAS demodulator.

Beacon
Navigation authorities around the world have installed DGPS radiobeacon networks that broadcast free GPS correction information. With the use of their built-in beacon demodulator and antenna, the VECTOR ST & PRO uses these real-time corrections to deliver accurate, reliable positioning when in range of a beacon.

Interface
The Vector ST & Pro, each feature two independent RS-232 serial ports and one RS-422 port. Any port may be configured freely for a variety of NMEA 0183 output sentences or for the input of RTCM correction data from an external source. The power supply and each communications port is optically isolated to ensure that hull electrolysis does not occur.

COAST ™ Technology
The Vector ST & Pro feature COAST™ technology that allows it to use old correction data for up to 40 minutes without seriously affecting positioning performance. This feature offers peace of mind and allows you to focus on more important issues than reliability of a differential signal.

Affordable GPS, WAAS,EGNOS and Beacon
CSI Wireless, an industry leader in the development and manufacture of positioning and wireless equipment, introduces the Evolution - the world’s first compact, cost-effective combination GPS, WAAS/EGNOS, beacon receiver.

GPS Sophistication
The Evolution uses a 12-channel chip set for reception of GPS and WAAS/EGNOS signals. The Evolution offers fast startup times and low power consumption, ideally suited for portable applications. Positioning performance is between 2 and 3 m accuracy with differential correction input.

With built-in support of both WAAS-compatible Space Based Augmentation Systems (SBAS) and DGPS beacon services, the Evolution will provide a differentially corrected position throughout much of the world’s populated areas.

SBAS Support
The US Federal Aviation Administration’s Wide Area Augmentation System (WAAS) is now undergoing rigorous final testing for its Initial Operation.

Capability
Other WAAS-compatible augmentation systems are also under development elsewhere such as the European Geostationary Navigation Overlay System (EGNOS) and the Japanese MTSAT Satellite-based Augmentation System (MSAS), among others. The Evolution provides compatibility for each of these free services.

Beacon Support
Navigation authorities around the world have installed DGPS radiobeacon networks that broadcast free GPS correction information. When in range of a beacon signal, the Evolution applies these differential corrections to deliver accurate, reliable positioning.

Interface
The Evolution features a simple dual serial port interface. It incorporates a straight MCX socket connector for input of both GPS/SBAS and beacon signals. In order to maintain volatile memory that contains satellite navigation information and to keep the real-time clock running, either a battery or super-cap may be used.

Power and differential lock LEDs are present on-board to provide a quick indication of receiver status. The Evolution features a convenient NMEA 0183 interface for configuration and monitoring system status. A suite of binary messages are also supported.
