Innovations
The core innovations in Satraka technology include:
- Antenna beam-tracking mechanism
- Frequency bandwidth expansion
- One-antenna solution
- Modular approach to design and manufacturing
In beam-tracking antenna field, there are currently two competing technologies: Mechanically Steered Antennas (MSAs) and Electrically Steered Antennas (ESAs). Both solutions are expensive and have technical performance issues.
MSAs rotate entire antenna structures, including a large parabolic reflector, for beam tracking. While they can offer high antenna gain and efficiency, MSAs cannot support satellite beam handovers, requiring two antennas at each user terminal.
ESAs, on the other hand, can perform seamless beam handovers with a single antenna. However, they exhibit very low antenna gain and efficiency, along with degraded radiation patterns when steering off the antenna boresight.
Satraka technology offers the best of both worlds by providing high antenna gain and efficiency (as good as MSA if not better) along with seamless beam handover (as good as ESA) from just one antenna structure. This is achieved through an innovative, patent-pending beam-tracking mechanism.
By implementing these innovations, the antenna structure and tracking mechanism are significantly simplified, resulting in a notable reduction in cost. Additionally, adopting a modular approach to design and manufacturing further reduces the cost of the antenna.
While preserving high gain and efficiency, all Satraka’s tracking antennas are designed for low size, weight, and power (SWaP), which are essential for mobility platforms.
Satraka antennas offer the industry the best combination of high technical performance and cost-effectiveness.
