SDRs for Philippine Coast Guard [INDODEF16-D3]

04 November 2016

The Philippine Coast Guard has selected Rohde & Schwarz (Hall A, Stand 117) to provide secure communications and radio monitoring equipment to enhance the reconnaissance, pursuit and communications capabilities of its 10 new Japanese-built Multi-Role Response Vessels (MRRVs).

The Rohde & Schwarz scope of supply includes both M3SR Series 4400 and Series 4100 software-defined radios, which ensure secure voice and data communications.

The M3SR Series 4400 radios provide continuous AM and FM transmission coverage in the VHF and UHF frequency range from 100-512MHz. The M3SR Series 4100 radios deliver reliable and easy to set up shortwave communications.

An automatic message-handling system is also part of the package. The MRRVs will have situational awareness through the Map Track, email, chat and file transfer features of the Postman III software.

Postman III enables efficient data transmission over radio networks by supporting IP-based applications. It has been optimised for communications over HF and VHF/UHF radio networks with variable data rates. Furthermore, because it is IP-based, it can interface with standard IP infrastructures such as LAN/WAN and satcom.

The DDF205 monitors radio emissions from 8kHz to 6GHz and covers direction finding of signals ranging from 20MHz to 3GHz. The DDF205 combines the new, highly integrated EB500 monitoring receiver with the accurate correlative interferometer DF method. This unique combination offers precise radio direction finding with sensitive radio monitoring capabilities. The DDF205 is compact and has low power consumption. It also features wideband DF antennas and the ability to be powered from a DC source.

The first MRRV, BRP Tubbataha, arrived in the Philippines in August 2016. The 44m-long vessels are being built by Japan Marine United Corp at its Yokohama Shipyard. Rohde & Schwarz subsidiaries in the Philippines and in Japan have worked together to co-ordinate the integration of the equipment package on the MRRVs.
