Accounting Policies [Abstract]
2023 10-K - Revision for correction of Immaterial Errors	2023 10-K - Revision for Correction of Immaterial Errors As stated in the Company's Annual Report on Form 10-K for the year ended December 31, 2023, which was filed on March 15, 2024, the Company corrected for errors that were immaterial to its previously reported consolidated financial statements. These errors were identified in connection with the preparation of the Company's consolidated financial statements for the year ended December 31, 2023, and related primarily to the adoption and implementation of Accounting Standards Codification (“ASC”) No. 606, Revenue from Contracts with Customers (“ASC 606”) on January 1, 2018, specifically, the assessment of performance obligations associated with the sales of antennas and airtime-related equipment. The Company evaluated the materiality of these errors both qualitatively and quantitatively in accordance with Staff Accounting Bulletin (“SAB”) No. 99, Materiality, and SAB No. 108, Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year Financial Statements, and determined that the effect of these corrections was not material to the previously issued financial statements. Therefore, the amounts in the previous period have been revised to reflect the correction of these errors.
Basis of Presentation	Basis of Presentation The accompanying consolidated interim financial statements of KVH Industries, Inc. and its wholly owned subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America. The Company has evaluated all subsequent events through the date of this filing. All significant intercompany accounts and transactions have been eliminated in consolidation. The consolidated interim financial statements have not been audited by the Company’s independent registered public accounting firm and include all adjustments (consisting of only normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of the financial condition, results of operations, and cash flows for the periods presented. These consolidated interim financial statements do not include all disclosures associated with annual financial statements and accordingly should be read in conjunction with the Company’s consolidated financial statements and related notes included in the Company’s annual report on Form 10-K for the year ended December 31, 2023 filed on March 15, 2024 with the Securities and Exchange Commission. The results for the three months ended March 31, 2024 are not necessarily indicative of operating results for the remainder of the year.
Significant Estimates and Assumptions and Other Significant Non-Recurring Transactions	Significant Estimates and Assumptions and Other Significant Non-Recurring Transactions The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of sales and expenses during the reporting periods. The estimates and assumptions used by management affect the Company’s revenue recognition, valuation of accounts receivable, valuation of inventory, expected future cash flows (including growth rates, discount rates, terminal values and other assumptions and estimates used to evaluate the recoverability of long-lived assets and goodwill), estimated fair values of long-lived assets (including goodwill, amortization methods and amortization periods), certain accrued expenses and other related charges, stock-based compensation, contingent liabilities, forfeitures and key valuation assumptions for its share-based awards, estimated fulfillment costs for warranty obligations, tax reserves and recoverability of the Company’s net deferred tax assets and related valuation allowance, and the valuation of right-of-use assets and lease liabilities. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances.
Foreign Currency Translation	Foreign Currency Translation The financial statements of the Company’s foreign subsidiaries located in Denmark, Singapore and Cyprus are maintained using the United States dollar as the functional currency. Exchange rates in effect on the date of the transaction are used to record monetary assets and liabilities. Revenue and other expense elements are recorded at rates that approximate the rates in effect on the transaction dates. Foreign currency exchange gains and losses are recognized within “other expense, net” in the accompanying consolidated statements of operations. The Company recorded net foreign currency exchange losses, which are comprised of both realized and unrealized foreign currency exchange gains and losses, in its accompanying consolidated statements of operations of $(21) and $(54) for the three months ended March 31, 2024 and 2023, respectively. The financial statements of the Company’s foreign subsidiaries located in the United Kingdom, Brazil, Norway, India and Japan use the foreign subsidiaries’ respective local currencies as the functional currency. The Company translates the assets and liabilities of these foreign subsidiaries at the exchange rates in effect at the end of each reporting period. Net sales, costs and expenses are translated using average exchange rates in effect during the period. Gains and losses from foreign currency translation are credited or charged to accumulated other comprehensive loss included in stockholders' equity in the accompanying consolidated balance sheets.
Recently Issued Accounting Standards and Accounting Standards Not yet Adopted	Recently Issued Accounting Standards and Accounting Standards Not yet Adopted There are no recent accounting pronouncements that have been issued by the FASB, that are not yet effective and that the Company expects would have a material impact on the Company's financial statements.
Fair Value Measurement	ASC Topic 820, Fair Value Measurements and Disclosures (ASC 820), provides a framework for measuring fair value and requires expanded disclosures regarding fair value measurements. ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 describes three levels of inputs that may be used to measure fair value: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. The Company’s Level 1 assets are investments in money market mutual funds. Level 2: Quoted prices for similar assets or liabilities in active markets; or observable prices that are based on observable market data, based on directly or indirectly market-corroborated inputs. The Company has no Level 2 assets or liabilities. Level 3: Unobservable inputs that are supported by little or no market activity, and are developed based on the best information available given the circumstances. The Company has no Level 3 assets. Assets and liabilities measured at fair value are based on the valuation techniques identified in the table below.
