    Cobham receives Inmarsat type approval for new terminals

    Cobham Explorer 323 and Explorer 6075LX terminals receive Inmarsat type approval

    Two Cobham SATCOM land satellite terminals have received Inmarsat type approval. The low-profile vehicular Cobham Explorer 323 BGAN terminal and the auto-point “fly-away” Cobham Explorer 6075LX VSAT terminal are now fully operational on the Inmarsat network with commercial shipments of each beginning immediately.

    The new Explorer 323 terminal represents the first class 12, electronically steerable terminal for use on Inmarsat’s L-band Broadband Global Area Network (BGAN). It combines the slimmest form factor of any vehicular BGAN terminal with a number of new innovative features and sets a new standard in robustness due to its lack of moving parts. In conjunction with Inmarsat’s highly reliable network, offering up to 99.9% uptime, it promises a new standard in mobile communications to organisations operating in remote locations across a wide array of industries.

    The class 12 terminal features speeds of up to 384kbps, support for BGAN (data and voice) and BGAN M2M (data) operations, and an integrated antenna and receiver, meaning only a rooftop unit is needed. Additionally, the Explorer 323 has an integrated Wi-Fi Hotspot for setup, management and data access. Developed to integrate seamlessly with Cobham’s PRISM PTT+ offering, the Explorer 323 will enable telemetry and voice communications as well as other uses in remote rail operations, utilities, mining, aid and NGO operations, agriculture, public safety and emergency response.

    Inmarsat has also approved the new auto-point ‘fly-away’ 0.75m Cobham Explorer 6075LX VSAT terminal for its high-speed Ka-band Global Xpress service. The new terminal offers the most reliable and stable connection in its class and features a simplified design, enhanced usability, quick setup and built-in WiFi. With a dynamic auto-pointing correction the terminal maintains its connection even in windy conditions or when pushed or moved, optimising its connection constantly. The Explorer 6075LX also features a considerable reduction in weight versus the Explorer 5075GX for greater portability and will support high-bandwidth applications in broadcasting, resilience and field-office operation.

    “We are proud to offer these two game-changing terminals to our partners and customers,” said Mike Carter, president of Inmarsat Enterprise. “Their launch follows an important period of industry consultation, innovation and collaboration between Cobham and Inmarsat. With the Explorer 323 ideal for vehicular tracking and communications and the Explorer 6075 optimised for high-bandwidth operations, both terminals improve upon their predecessors and are set to make ultra-reliable connectivity easier to access in the remotest areas, wherever it is needed most.”

    “These two new terminals from Cobham prove that there continues to be innovation occurring in both our L-band and Global Xpress networks,” said Todd McDonell, president of Inmarsat Global Government. “For government users, the 6075LX (or GX6075) provides a fast to set up, easy-to-use, automatic acquisition broadband terminal ideal for first responders who need to access communications at a scene quickly.

    “In addition, the Explorer 323 provides government users with a way to maintain on-the-move connectivity regardless of the situation,” McDonell said. “When fixed networks become disabled or degraded, due to events such as natural disasters, the Explorer 323 provides an ideal, low-profile system for routing radio and data connectivity and can be integrated with the emergency services’ existing radio and data networks. We thank Cobham for bringing these products to market. We believe that they will help to deliver new capability for a number of government departments and agencies.”

    Inmarsat owns and operates mobile telecommunications satellite networks around the globe, and holds a multi-layered, global spectrum portfolio covering L-band, Ka-band and S-band.

    Inmarsat has provided global, L-band services for many decades, which are used by governments, the maritime and aviation industries, and commercial users on land, in sectors ranging from mining and agriculture to rail and transportation.

    The frequencies used by Inmarsat to deliver these services are different to those used for GPS/GNSS. All terminals approved for use over Inmarsat’s L-band network (and their other networks) conform to international standards.

    In the case of GPS, Inmarsat has exceed these standards by a considerable margin.

    After extensive ground and space testing, the SES-5 GEO satellite has entered into the European Geostationary Navigation Overlay Service (EGNOS) operational platform, broadcasting EGNOS Signal-In-Space (SIS), according to the European GNSS Agency (GSA).

    SES-5 — which replaces Inmarsat-4F2 — will ensure reliable EGNOS services until 2026. It has been introduced through EGNOS System Release V241M, which will enable a range of performance improvements. In particular, EGNOS will offer even greater stability during periods of high ionospheric activity.

    “SES-5 is the first step of the complete renewal of the EGNOS Space Segment, securing the EGNOS services for the next decade and the future transition to the dual-frequency multi-constellation services,” said Carlo des Dorides, GSA Executive Director. “It will be completed by the introduction of the ASTRA-5B signals and the procurement of a new EGNOS payload which are both planned for 2016.”

    SES-5, carrying EGNOS L1 and L5 band payloads, was launched in July 2012. The integration of a second EGNOS SBAS L1/L5 band payload on SES ASTRA-5B GEO satellite is currently ongoing. The introduction of this second SES GEO satellite for EGNOS is planned at the end of 2016. SES won the contract following an open-tender procedure.

    “SES is looking forward to many years of successful operation in delivering EGNOS services to the European citizens and beyond,” said Ferdinand Kayser, chief commercial officer at SES.

    EGNOS is operated by the European Satellite Services Provider (ESSP), under contract by the GSA on behalf of the European Commission.

    NovAtel Inc. has introduced the GPS-713 pinwheel antenna, available in two configurations: the standard GPS-713-GGG-N and the L-Band capable GPS-713-GGGL-N. 

    Both antennas provide enhanced Inmarsat interference rejection, allowing tracking of GNSS signals in the presence of high-powered Inmarsat transmitters typically found on marine vessels. The antennas receive GPS L1, L2, L5; GLONASS L1, L2, L3; BeiDou B1, B2; and Galileo E1, E5a/b frequencies, optimizing global satellite tracking capabilities. Customers can use either antenna for GPS-only or multi-constellation applications, providing excellent flexibility and reduced equipment costs, NovAtel said.

    Designed for baselines of any length and easy installation, the phase center offset of these antennas remains constant as the azimuth and elevation angle of the satellites change. The antenna shares the same form factor as other NovAtel GPS-700 series antennas, and is enclosed in a durable, waterproof housing.  Its compact, lightweight size makes it suitable for a wide variety of environments and applications.
