Astra Microwave Products designs, develops, and manufactures microwave sub-systems for the defence, space, telecommunication and meteorology sectors.
Product range includes radar electronics, sub-systems for missiles, electronic warfare, space and telemetry sub-systems, as well as satcom terminals, telecommunication and monolithic microwave integrated circuits (MMICs).
Total solutions for radar sub-systems
Astra is able to design, develop and produce total radio-frequency (RF) and microwave sub-systems for radar systems.
Astra's products have been used as part of both Indian and international radar programmes and were developed according to the required military and aerospace standards.
Astra's radar sub-systems include TR modules in very high-frequency (VHF), ultra high-frequency (UHF), L, S, C, X Ku and Ka bands, Central units - L & S Bands, Receiver Exciters up to Ka band, Array Group receivers, electronic beam forming units, low-power microwave sub-systems and high-power limiters.
Solutions for electronic warfare
Astra is able to develop, design and produce total RF and microwave sub-systems for electronic warfare application. Astra's products have been used as part of many naval programs and have been able to meet the demanding needs of the naval platforms.
Astra's EW sub-systems include antennas, front end receivers, up/down convertors, DIFM and special components that include power dividers, pre-filters, etc.
Sub-systems for missile
Astra supplies clients with an extensive missile electronics sub-systems range. Its products feature phased array based seeker sub-systems, radio proximity fuses (RPF), command guidance units (CGU) and transponders.
Astra has produced a range of telemetry sub-systems such as:
- Data and video telemetry transmitter systems for light combat aircraft (LCA)
- 1W and 10W telemetry transmitters for missile applications
- Telemetry transponders
- Tele-command encoders, decoders and receivers
- Auto track antenna systems
Sub-systems for the Indian space industry
Many of Astra's products are prominent within the Indian space industry and can be found on-board Indian Space Research Organisation (ISRO) satellites, such as the Geostationary Satellite (GSAT), the Indian National Satellite (INSAT), the Radar Imaging Satellite (RISAT) and the Indian Remote Sensing Satellite (IRS).
Astra's selection of ground-based and S-level or on-board sub-systems include:
- TR Modules in VHF, UHF, L, S, C, X Ku and Ka bands
- High Power PIN Diode Switches
- Integration block
- Switch Matrices
- Beacon sources
- QPSK and BPSK Transmitters in X and S Band
- C & S Band Transponders
- C and Ku Band Receivers
Mobile satellite service type-D terminals for disaster communication
Astra has successfully developed mobile satellite service (MSS) type-D terminals for disaster situations.
The demand assigned multiple access (DAMA) terminals offer point-to-point connectivity for both voice and data-based communications, operate in S-band, have considerably fast deploy times and are extremely portable.
Automatic weather stations for remote data access
In collaboration with ISRO, Astra has installed and developed automatic weather stations (AWS) within more than 1,200 remote Indian locations, where various data parameters can be recorded, such as atmospheric pressure, solar radiation levels, wind-speed, rainfall and temperature.
The stations send locally collected data to a central location using a satellite with Astra's transmitter, data logger and uplink antenna. The information is further analysed by the Indian meteorology department and other select institutes.
