Alternative Position Navigation and Timing Challenge


NAWC seeks participation in the 2021 NAWC ANTX (May 2021) in the area of Alternative Positioning, Navigation and Timing (APNT) arena to support Distributed Maritime Operations (DMO) under the Joint War At Sea (JWAS) initiative. The US Armed Forces have become reliant on GPS for precision navigation from foot mobile infantry to high-end precision weapons. This reliance on GPS will no doubt be exploited by near peer competitors in the event of a future conflict. These factors combined give rise to the need for the APNT capability. APNT is defined as the ability to provide operational Navy forces continuous access to position, velocity, attitude and time information with confirmed integrity and sufficient accuracy to perform their mission under the complete range of threat conditions. Threat conditions include, but are not limited to GPS degradation, GPS denial, and GPS deception. The approach areas of interest include:

  • PNT Source selection: Enables the operator to include or exclude discreet PNT sources
  • PNT Source Abstraction: Translates PNT source data and metadata into a standard interface protocol, separating the specific sensor implementation from the downstream data processing.
  • Navigation Functions: Derive PNT data or metadata from one or more core or exploitable sensors.
  • Integrity Algorithms: Route PNT Source data and metadata through the appropriate set of integrity fault and information assurance fault detection algorithms.
  • Fault Extraction: Functions that discriminate and exclude PNT Source data and metadata based on integrity thresholds defined in integrity algorithms.
  • Data Fusion: Functions that instantiate state estimation algorithms.
  • PNT Propagation: Function that translates and distributes assured or unprocessed position, velocity, attitude or time data and metadata into native PNT consumer interfaces.


Application Deadline. Applications for participation in the NAWC ANTX (May 2021) will be accepted until 2359 EST on 28 February 2021. Invitations to participate in the experiment are anticipated to be issued via e-mail no later than 2359 EST on 27 March 2021. Responses to invitations will be due no later than 2359 EST on 10 April 2021.

As part of the initial application to participate in the NAWC ANTX event, prospective candidates will need to submit the following:

  • Online web application
  • White paper (template available here) not to exceed 6 pages, describing their system/technology. The submitted technologies will be evaluated on; (1) estimated Technology Readiness Level (TRL), (2) the system’s potential uses for NAVAIR, and (3) applicability to the warfighter. Therefore, submitted white papers must address these factors.
  • PowerPoint packet (template available here) includes one quad chart slide, and four (4) additional slides that can be used for any additional pictures or videos.


All submitted applications will be reviewed by the Government. Technologies that will be targeted will be determined following review of the white papers by the Government for inclusion in the NAWC ANTX event. Not all applications will be given the opportunity to participate in the ANTX event.

The Government will coordinate NAWC ANTX event range set-up and provide coordination assistance for airworthiness certification and frequency allocation as required.

The NAWC ANTX event venue is located at the Naval Air Station Patuxent River, Maryland or Webster Outlying Field (WOLF) in Saint Inigoes, Maryland.

Successful participation in the NAWC ANTX event may result in the award of an Other Transaction (OT) agreement (under authority of 10 U.S. Code Section 2371 or 2371b) or award of a procurement contract for experimental purposes (10 U. S. Code Section 2373) or a combination of these authorities. The Government reserves the right to make multiple, one, or no awards as a result of this event.


Terms and Conditions:

These terms and conditions apply to all participants in the NAWC ANTX event.

Agreement to Terms.
