Satcom Direct has mounted its Plane Simple Ka-band satcom antenna on the company’s Gulfstream 550, the first such installation on a business jet. Testing of the Ka-band satcom system will be done during normal flight operations in the G550 to validate the prototype satcom terminal and “finalize the design for optimized functionality,” according to Satcom Direct.

The Plane Simple system operates on Inmarsat’s Jet ConneX broadband satcom service, which is supported by Inmarsat’s Global Xpress satellite constellation. This Ka-band antenna is the second Plane Simple system, with the first developed for Ku-band satcom. Plane Simple systems consist of two LRUs, the antenna mounted on the airplane’s empennage and the SD modem unit.
