The History of Glocom

In 2017, Glocom developed GR-8520VU High Capacity Data Radio (HCDR).

Recently the new doctrine of network-centric warfare prompts many countries and companies to develop the high speed radio with IP-based mobile ad-hoc networking that transmits mission-critical voice, data and video quickly and efficiently.

On the way of developing this radio, we analyzed the various radios worldwide of the same kind as compared with each other, and designed the optimized system. This radio is sub-compatible with GR-8520 radio, and is able to be installed in vehicles and shipborne. In addition, the peripheral accessories including handset are compatible with the standard products. The dimension and weight are suitable for handling and the installation is convenient.

Year 2016 was the most difficult, but innovative year for Glocom. This year, Glocom developed GR-8100HV HF/VHF manpack radio.

On the worldwide scale HF and VHF radios were integrated, various waveforms were competitively developed, a great change occurred. Glocom mobilized all the know-how and new technologies accumulated until now to design, develop and test GR-8100HV HF/VHF manpack radio and end users experienced the radio for six months in the real field. This radio is interoperable with GR-150, GR-250 and GR-310 radios, both the weight and volume are reduced to one-third above. Interfaces with user and external systems are reinforced. It is recently recognized that GR-8100HV radio is the Smallest, Lightest and Fastest HF/VHF manpack radio in the world, and Glocom is very proud of that it has no comparable competitor in price vs. performance.

In 2015, GS-2600-01 UAV/USV Video, Telemetry/Control System was developed by Glocom as orders of companies that are professional for developing UAV or USV. This system can be installed in various kinds of strategical or tactical UAV/USV. It has advantages including simple installation, high reliability, secure transmission and ECCM functionality.

Staring from 2006, Glocom exhibited its products 3 times in the Defense Service Asia weapons exhibition which is held in Malaysia every 2 years. Through the exhibition, Glocom is keeping itself abreast of the latest international trends and promoting cooperation and exchange with overseas customers. So far a considerable part of Glocom's customers has been the companies that came to know of Glocom's reputation through the exhibition.

In 2004, Glocom began to develop GR-300 VHF/UHF ECCM radio to be supplied to domestic and overseas customers. Now the radio entered the mass production stage after passing the field test. It operates in a broad band ranging from 30 to 512 MHz and is completely compatible with the already supplied GR-200 VHF radios in the same frequency bands. It is also compatible with old-generation radios used in airplanes, ships, vehicles, and infantry units, in the clear mode. Therefore, it is regarded as a multifunction radio that satisfies the requirements of both continuity and innovation. The picture show GF-300 VHF/UHF ECCM radio.

In 2002, a new mass production facility for GR-200 VHF ECCM radio was set up, equipped with SMT equipment, measuring equipment, and testing equipment. Its production capacity in one production cycle was 500 sets with 45 employees. In 2005, Glocom produced and delivered 375 sets of GR-200 VHF ECCM radios to an overseas customer for the first time. In that year, Glocom began manufacturing peripheral devices such as remote control units. Now Glocom manufactures more than 1,500 sets of radios and various kinds of peripheral devices every year. In 2004, Glocom unveiled a newly developed HF ECCM radio GR-100 and its accessories. In the latter half of that year, Glocom began to manufacture HF 100W amplifier GR-101C/automatic tuning unit GR-102C and vehicle power supply systems. In 2004, Glocom delivered 10 sets of HF ECCM radios. Until now it has sold 550 sets to customers worldwide. In 2004, Glocom also developed a comprehensive vehicle radio system equipped with integrated VHF and HF radios. The system won out in a domestically-held competitive bidding and was chosen as a standard communication equipment to be installed in combat vehicles, airplanes, and ships.

The picture above shows the GR-100 HF ECCM radio developed at that time.

From 1997 to 1998, Glocom's priority was to develop GR-200 VHF ECCM radio (then called PDS-200). This project was carried out on the basis of a development contract concluded with another company. Glocom won out in that competitive bidding, as our project was better than those from other producers in terms of delivery conditions, technology, payment terms, overall cost reduction, and system performance. The development and field test of GR-200 VHF ECCM radio was conducted in the late 1998 and technical and design documents necessaries for mass production were immediately drawn up. The picture shows GR-200 VHF ECCM radio.

Glocom was established in 1996. In its early time, Glocom involved in the research and development to modernize old-generation radars with new technologies to enhance their combat usability and increase their lift spans. So far Glocom modernized and delivered to customers more than 50 strategic and tactical radars (altogether 6 kinds). Glocom has long maintained relations of strategic partnership and cooperation with defense companies that produce radars and other reconnaissance and sensing equipment, military vehicles, vessels, airplanes, and helicopters, and other military hardware.
