Revenue from Contract with Customer [Abstract] |
Revenue from Contract with Customer (ASC 606) | Revenue from Contracts with Customers (ASC 606) The Company adopted ASC 606 on January 1, 2018 using the modified retrospective method for all contracts not completed as of the date of adoption. The adoption of ASC 606 represents a change in accounting principle that is expected to more closely align revenue recognition with the delivery of the Company's products and services and is expected to provide financial statement readers with enhanced disclosures. In accordance with ASC 606, revenue is recognized when a customer obtains control of promised products and services. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these products and services. Disaggregation of Revenue The following table summarizes net sales from contracts with customers for the three and six months ended June 30, 2019:
|  | Three Months Ended |  | Six Months Ended
|  | June 30 |  | June 30
|  | 2019 |  | 2018 |  | 2019 |  | 2018
Mobile connectivity product, transferred at point in time |  | $ | 6,697 |  |  | $ | 6,731 |  |  | $ | 12,374 |  |  | $ | 13,401 |
Mobile connectivity product, transferred over time |  | 1,371 |  |  | 1,372 |  |  | 2,756 |  |  | 2,622 |
Mobile connectivity service |  | 22,906 |  |  | 20,901 |  |  | 44,417 |  |  | 41,034 |

Total net sales |  | $ | 39,235 |  |  | $ | 38,632 |  |  | $ | 75,270 |  |  | $ | 74,037 |
Revenue recognized during the three months ended June 30, 2019 and 2018 from amounts included in contract liabilities at the beginning of the period was $1,254 and $1,193, respectively. Revenue recognized during the six months ended June 30, 2019 and 2018 from amounts included in contract liabilities at the beginning of the period was $2,590 and $2,408, respectively. For mobile connectivity product sales, the delivery of the Company’s performance obligations, and associated revenue, are generally transferred to the customer at a point in time, with the exception of certain mini-VSAT contracts which are transferred to customers over time. For mobile connectivity service sales, the delivery of the Company’s performance obligations and associated revenue are transferred to the customer over time. For inertial navigation product sales, the delivery of the Company’s performance obligations, and associated revenue, are generally transferred to the customer at a point in time. For inertial navigation service sales, the Company's performance obligations, and associated revenue, are generally transferred to customers over time. Business and Credit Concentrations Concentrations of risk with respect to trade accounts receivable are generally limited due to the large number of customers and their dispersion across several geographic areas. Although the Company does not foresee that credit risk associated with these receivables will deviate from historical experience, repayment is dependent upon the financial stability of those individual customers. The Company establishes allowances for potential bad debts and evaluates, on a monthly basis, the adequacy of those reserves based upon historical experience and its expectations for future collectability concerns. The Company performs ongoing credit evaluations of the financial condition of its customers and generally does not require collateral. No single customer accounted for 10% or more of the Company's consolidated net sales for three or six months ended June 30, 2019 or 2018 or accounts receivable at June 30, 2019 or December 31, 2018. Certain components from third parties used in the Company’s products are procured from single sources of supply. The failure of a supplier, including a subcontractor, to deliver on schedule could delay or interrupt the Company’s delivery of products and thereby materially adversely affect the Company’s revenues and operating results.
