Skyforce Avionics Ltd. is a United Kingdom–registered avionics company based in West Sussex, England. It operated as an independent UK manufacturer of GPS moving-map displays in the mid-1990s and was acquired by AlliedSignal in 1998 (reporting 1997 sales of roughly $2 million); following the 1999 AlliedSignal–Honeywell merger it became a subsidiary of Honeywell International Inc. (NASDAQ: HON). No current standalone employee count or revenue figures are published; its financials are consolidated within Honeywell's Aerospace segment. Note that this entity is unrelated to the Israeli autonomy/AI startup "Skyforce" founded in March 2025.
Products / operations. Skyforce Avionics is an operating company, not a shell. It developed the Skyforce Skymap and Tracker hand-held and panel-mounted GPS moving-map units (later sold under Honeywell's Bendix/King brand), and subsequently the Skyforce Observer (multi-workstation mission-management and mapping system for search-and-rescue, airborne law enforcement, and military-role platforms) and Sentinel (single-workstation mapping/situational-awareness system for HEMS and executive helicopters). Honeywell has described the West Sussex site as its "design centre of excellence for mission systems," and Honeywell still markets Observer/Sentinel data-update services under "Skyforce Products."
Patent-litigation posture. The tracked data show 0 cases as plaintiff and 2 as defendant, the classic signature of an operating company being sued rather than a patent assertion entity. Both appearances arise from a single dispute brought against it and its parent; neither case sits in a notoriously plaintiff-friendly venue such as the Eastern District of Texas.
Notable cases. In Furuno Electric Co., Ltd. v. Honeywell International Inc. et al., filed 30 September 2011, Furuno asserted four U.S. navigation patents (Nos. 6,084,565; 7,089,094; 7,095,367; 7,161,561) against Skyforce and Honeywell in the District of Oregon, Portland Division (3:11-cv-01196), and in parallel ITC Section 337 investigation 337-TA-810. Both proceedings were terminated in February 2012 after a joint settlement. Honeywell had earlier sued Furuno and other marine-navigation vendors over separate patents.
