Introduction The CERTAIN unmanned aerial systems test range consists of an airspace agreement between NASA Langley

Research Center, Langley Air Force Base and the Federal Aviation Administration to fly in class D airspace up to 400 feet. The range encompasses 500+ acres on NASA Langley and is intended to conduct flight testing on small unmanned aerial systems in urban environments.

To supplement ongoing research in small UAS navigation techniques in urban areas where GNSS and GPS reception is limited CERTAIN is undergoing the installation of an alternative system to GNSS to provide coverage across NASA

Langley Research Center to a mobile aerial receiver onboard a small UAS. This local positioning system shall consist of a (1) series of ground‐based beacons strategically located across the center and a (2) mobile aerial receiver unit which will meet the specifications outlined herein.

This SOW will cover the entire deployment of the system including design, engineering, installation, calibration, network validation, and maintenance of the system for a period of 3 years.

Scope of Work The contractor shall provide the following:

1. Design and Installation of up to 10 LPS transmitters

a. RF design to maximize LOS and BLOS performance

b. Site candidate evaluation and final selection

c. 3 year maintenance and operations contract of transmitter sites. Ownership will shift to NASA

Langley following the 3 year term beginning after award.

d. Mechanical drawings of ground equipment.

e. Materials procurement (e.g., antennas, cables, weather proofing, mounting hardware, grounding kits)

f. Installation of power, where required

g. LPS transmitter installation.

i. Contractor shall submit site selection locations of transmitters for review and approval by the government.

ii. Contractor shall submit to the government standard methods for mounting and power requirements for each of the devices in the proposal.

iii. The government will provide interface hardware and power to the approved locations prior to installation by the contractor.

iv. The Government will provide power within 10 feet of approved locations.

v. Contractor shall provide for connection from the transmitter to the government provided location.

h. Appropriate connectivity for O&M network capabilities

2. Aerial receiver hardware necessary to equip a minimum of 10 unmanned aerial systems for operations with the local positioning system

3. Contractor shall submit an initial test plan to ensure that LPS meets the technical requirements outlined in

Technical Specification 6 and 7, for both terrestrial and aerial operation and characterize expected network performance in service area

4. Contractor shall submit a Health and Safety plan for approval by the government prior to onsite installation of transmitters.

5. Contractor shall submit a proposed installation schedule within 15 days of the award of the contract. The contractor shall also submit a means and methods narrative for each of the transmitters to be installed for approval by the government.

6. Contractor shall submit a proposed Service, Operations and Maintenance plan for the LPS which will include system repair and monitoring. Initial servicing response time shall be within 1 day and servicing and repair shall be within 1 week. The service, operations & maintenance shall be for a 3 year period.

Technical Specifications The contractor shall provide a system to meet the following:

1. Shall provide a geo‐referenced three‐dimensional position estimate onboard a mobile aerial platform at a minimum rate of 1 Hz.

2. Shall be FCC Part 90 compliant and type certified.

3. Shall be ground‐based infrastructure (e.g. beacons) that must operate on standard 110VAC 60Hz input, must be compliant with all NEC standards, and have controllable output transmission power.

4. Shall consist of no greater than 10 stations to meet this requirement.

5. Shall be capable of providing local positioning data across the entire NASA Langley Research Center as outlined in the orange perimeter in Figure 1.

6. For outdoor operations, the system shall have an accuracy of better than 5 meters in the vertical channel and 7 meters in the horizontal channel.

7. For normal indoor operations, the system shall have an accuracy of better than 5 meters in the vertical channel and 12 meters in the horizontal channel.

8. Shall include all receiver hardware necessary to equip a minimum of 10 unmanned aerial systems for operations with the LPS

9. The air vehicle receiver component shall weigh no greater than 1 kg.

10. The air vehicle receiver component shall operate on a DC input voltage ranging from 8‐18VDC with less than 3 watts of power

11. The air vehicle receiver component shall be capable of operating completely independent of any GNSS.

GNSS may be used for receiver initialization, but not during operations.

12. The air vehicle receiver component shall be capable of outdoor operations in normal types of weather

13. The air vehicle receiver component shall be capable of interfacing via USB, UART, or Bluetooth

14. Shall allow for continuous operation during missions of at least 8 hours in length.

Government Furnished Information & Property

1. Upon reception of design proposal the Government will have 2 weeks to provide feedback to contractor regarding site selections.

2. The Government will provide power within 10 feet of approved locations.

3. The Government shall provide a means to secure LPS equipment to site locations based upon contractor furnished standard mounting documentation

Technical Acceptability Criteria

1. Proposed Installation completion date of December 1st , although the government would find value in an earlier completion date.

2. Shall consist of no greater than 10 stations to meet this requirement although the government would find value in meeting the technical specifications of the LPS with less stations.

3. Shall be capable of providing local positioning data across the entire NASA Langley Research Center as outlined in the orange perimeter in Figure 1 although the government would find value in a system that costs significantly less while providing a tolerable amount less of coverage.

4. For outdoor operations, the system shall have an accuracy of better than 5 meters in the vertical channel and 7 meters in the horizontal channel but the government would find value in an increase in accuracy.

5. For normal indoor operations, the system shall have an accuracy of better than 5 meters in the vertical channel and 12 meters in the horizontal channel but the government would find value in an increase in accuracy.
