مقدمة
We invite qualified SATCOM system UGV manufacturers and service providers to propose a compact, rugged, field-deployable satellite communication solution to support secure command & يتحكم, telemetry, and real-time ISR video transmission between an Unmanned Ground Vehicle (UGV) and a portable/handheld Ground Control Station (جي سي اس).
The system shall support full-duplex mobile satellite communications under contested, harsh, and high-mobility tactical conditions.
نظرة عامة على النظام (High-Level)
The proposed solution shall consist of:
UGV-Mounted Satellite Terminal
- Low-profile antenna with embedded modem.
- Designed for integration with the onboard mission computer.
Handheld GCS Terminal / Backpack Terminal
- Battery-powered, rugged terminal interoperable with the UGV terminal
Supported Bands (Vendor may propose any):
Primary: Ku-Band or Ka-Band LEO satellite networks.
- تكرار: 10.7–12.75 GHz (الوصلة الهابطة), 13.75–14.5 GHz (الوصلة الصاعدة), intended for LEO service.
Alternate: S-Band satellite networks
- تكرار: 2 - 4 غيغاهيرتز, Intended for government/Military satellite service.
