Product Details

Remote Sensing Satellite Tracking Antenna

Comtech has developed a cost-effective X/Y antenna pedestal technology that specialises in precision antenna tracking. Comtech Ground Systems are specifically designed for low and medium earth orbits that support Remote Sensing, Earth Observation, and TT & C applications.

Comtech Ground Systems offer a range of X/Y tracking antennas from 30 centimeters to 14 meters coupled with our installation expertise and worldwide support in extreme environments such as the Arctic, Middle East, and South East Asia. Comtech provides a complete satellite and tracking solution for your ground stations.

Radomes

Comtech Ground Systems’ cost-effective radome manufacturing technology can be delivered quickly, are easy to install, and RF tuned for the customer’s mission. Comtech Ground Systems’ geodesic radomes and their spherical radomes offer the very best antenna environmental protection possible against all elements at a very competitive price.

T1 Deployable X/Y System

Based on Comtech Ground Systems’ very successful and reliable Type 1 X/Y system, this variant offers capacity to 1.8m in a deployable format suitable for L, S, X, C, Ku, Ka and Q bands. This is achieved by providing a folding quad-pod base and split casings to provide easily assembled sub components at manageable weights.

Transportable Systems

The innovative transportable antenna systems are designed for transportation to any global site, with prompt setup times unique to their trailer based all-in-one design. The RF and Servo system of the antennas are not modified by the trailer mount, and the systems come with all appropriate road worthiness certifications and can be used with standard HGV coupling.

If required, space is provided for Client supplied equipment in the RF racks. These systems are ideal for rapid deployment scenarios, and can be tailored to suit your needs.

Product Features

Remote Sensing Satellite Tracking Antenna

30 centimeters to 14 meters antenna size
X/Y axis configuration (Type 000 through Type 6 for increasingly larger dishes)
Transmit/receive feed technologies through V-band
Designed for tracking LEO, MEO, HEO and GEO spacecraft
Applications include Earth Observation, Remote Sensing, Communications and TT&C functions
Lights-out operation, including ethernet (TCP/IP) and M&C software is provided with Linux-based M&C system, includes SNMP and XML support
Program and Auto Track Performance Effective program track capabilities that utilize ephemeris data in the form of Two Line Element (TLE) data and other formats
Autotrack Capabilities:
- Low loss mode coupler tracking system for high frequencies and larger aperture antennas that does not affect G/T performance
- Software assisted autotrack – the low velocity tracking dynamic of the X/Y allows the implementation of real time signal level peaking throughout the track by utilizing unique tracking algorithms to control the servo control system
