Title 14 - Aeronautics and Space
(a) To each user there will be an initial non-refundable administrative charge of $25,000 which is applicable toward TDRSS operational services. (b) The procedure for billing and payment of standard TDRSS services is as follows: (1) The calendar year is divided into two service periods, January through June and July through December. The charge for TDRSS service will be determined in October for the succeeding calendar year. (2) The estimated cost of service, January through June period, will be due the previous July 1, and will be billed 60 days prior to the payment due date. (3) The estimated cost of service, July through December period, will be due the previous January 1, and will be billed 60 days prior to the payment due date. (4) Adjustments to the amounts prepaid will be made to the succeeding billings as the actual service time is tabulated. Amounts due to the user will be credited to the next service period or refunded to the user if no more service is to be provided. (5) The total estimated cost of all standard pre-launch services such as mission planning, documentation, link analysis, testing, computer, human resources, etc., with the exception of TDRSS operational services, will be paid to the Government prior to NASA rendering such services. This advance payment will be applied as a credit to the charges billed for post-launch TDRSS operational services as specified in paragraphs (b) (1) through (4) of this section. (c) Payment schedules for mission unique services will be mutually developed between NASA the user on a case-by-case basis, dependent upon level of engineering effort, long-lead items, special communication services or other considerations. Payment will generally be made prior to NASA incurring a cost for mission unique service. (d) Late payments by the user will require the user to pay a late payment charge equal to 1
