Description of Business	Description of Business KVH Industries, Inc. (together with its subsidiaries, the Company or KVH) designs, develops, manufactures and markets mobile connectivity products and services for the marine and land markets. KVH’s satellite-only and hybrid products enable marine customers to receive data, voice, and value-added services via satellite, cellular, and shore-based Wi-Fi networks onboard commercial, leisure, and military/government vessels. In addition, the Company’s in-motion television terminals permit customers to receive live digital television via regional satellite services in marine vessels, recreational vehicles, buses and automobiles. KVH sells its products through an extensive international network of dealers and distributors. KVH also sells and leases products to service providers and end users. KVH’s service sales represent primarily revenue earned from satellite Internet airtime services. KVH provides, for monthly fixed and per-usage fees, satellite connectivity encompassing broadband Internet and Voice over Internet Protocol (VoIP) services, to its TracNet-H series and TracPhone V-series customers via KVH’s global high-throughput satellite (HTS) network. Cellular airtime service increasingly supplements KVH’s satellite-only airtime revenue following the July 2022 launch of the KVH ONE hybrid network and TracNet H-series terminals. This product and service combination integrates global satellite service with KVH-provided cellular service in more than 150 countries, along with shore-based Wi-Fi access. AgilePlans, KVH’s connectivity as a service offering, is a monthly subscription model that provides global connectivity to commercial maritime customers. The subscription includes the choice of satellite-only and hybrid terminals, airtime data service, VoIP, daily news, subsidized shipping and installation, and global support for a monthly fee with no minimum contract commitment. KVH offers AgilePlans subscribers a variety of airtime data plans with varying data speeds and fixed data usage levels with per megabyte overage charges. These airtime plans are similar to those the Company offers to customers who elect to purchase or lease a TracNet H-series or TracPhone V-series terminal. The Company recognizes the monthly AgilePlans subscription fee as service revenue over the service delivery period. The Company retains ownership of the hardware it provides to AgilePlans customers, who must return the hardware to KVH if they decide to terminate the service. Because KVH does not sell the hardware under AgilePlans, the Company does not recognize any product revenue when the hardware is deployed to an AgilePlans customer. KVH records the cost of the hardware used by AgilePlans customers as revenue-generating assets and depreciates the cost over an estimated useful life of five years. Since the Company is retaining ownership of the hardware, it does not accrue any warranty costs for AgilePlans hardware; however, the Company expenses any maintenance costs on the hardware in the period these costs are incurred. Service sales also include the distribution of commercially licensed entertainment, including news, sports, music, and movies to commercial customers in the maritime, hotel, and retail markets through the KVH Media Group, along with supplemental value-added services. In addition, KVH earns monthly usage fees from third-party satellite connectivity services, including voice, data and Internet services, provided to its Inmarsat and Iridium customers who choose to activate their subscriptions with KVH. Service sales also include sales from product repairs and extended warranty sales. On August 9, 2022, the Company sold its inertial navigation business to EMCORE Corporation for gross proceeds of $55,000, less specified deductions and a holdback of $1,000 and subject to a working capital adjustment. The holdback was released to the Company on August 17, 2022. On August 9, 2022, the Company also entered into a Transition Services Agreement with EMCORE, pursuant to which the Company agreed to provide certain transition services to support the continued operation of the inertial navigation business for six months following the sale with two extension options of three months each. The fee is comprised of both fixed monthly fees of approximately $100 as well as variable amounts for certain additional services with escalation increases on the fixed and variable rates for each extension option. The working capital adjustment is expected to be finalized in the fourth quarter of 2022. The Company does not have any continuing involvement in these operations other than short-term transition services, which are being recorded in other income in continuing operations. The Company determined that the sale met the requirements for reporting as discontinued operations in accordance with Accounting Standards Codification (ASC) 205-20. Please see Note 18 for the discontinued operations disclosures.
