TRACKING MOUNTS

Requirements Document

For

704th Test Group/846th Test Squadron

29 March 2021

1.0 PURPOSE

The Holloman High Speed Test Track (HHSTT) collects high speed imagery of test items traveling up to

10,000 feet per second along a 10-mile long sled track. High speed video recording is required to provide data for scientific design, test, evaluation and analysis. Tracking mounts are regularly used to track test articles and collect customer data. Thirty year old Kineto Tracking Mounts (KTM) are currently being used and many of the components are no longer working. Due to the age of the KTM’s, many of the needed positioning and servo control components are obsolete. Replacing the KTM’s with lightweight, high speed optical systems provides the 846 Test Squadron with up to date tracking systems able to integrate with other updated imaging components. New tracking mounts will improve and modernize the

HHSTT’s optical measurement capabilities.

2.0 SCOPE

The contractor shall provide three (3) tracking mounts meeting the specifications below.

2.1 Mechanical Specifications

Overall system must weigh less than 180lbs

Capable of being lifted with a two man lift

Capable of being configured to a permanent pedestal

Capable of being configured to a temporary pedestal and tripods

Manufactured to MIL-STD-810 for temperature, solar radiation, rain, and sand/dust o Operating temperature, specifications 501.5 & 502.5, operating range from 10 degrees F to 120 degrees F o Solar Radiation, specification 505.5, external components must be able to withstand the levels in 505.5 at the ground level, not space atmosphere o Rain, specification 506.5, equipment must be sealed well enough to keep rain out of the pedestal electronics o Sand and Dust, specification 510.5, equipment must be sealed to keep dust/sand out of internal pedestal electronics

System must be capable of running single phase 110VAC

2.2 Payload

System must be able to handle a camera payload of up to 200 lbs.

System must be configured with a way to mount a camera or platform to the pedestal

2.3 Rotation

Direct drive closed loop servo

270 degrees of azimuth rotation

180 degrees of elevation rotation

Controllable angular velocity from 0 to 120 deg/sec.

Controllable angular acceleration of 0 to 120 deg/sec/sec

Must have external connection to encoder data

Must be able to interface external position control to pedestal

2.4 Encoder

Minimum encoder resolution of 19 bits

Minimum position accuracy of 20 arc-seconds

Direct encoder output is required. This output must be a parallel output and not in a serial format

2.5 Slip Rings

Power, trigger, timing, and video feeds (HD-SDI or NTSC) must be fed through the slip rings

117VAC and 60 Hz power required

Two slip ring pairs must have timing (IRIG) for cameras

Two slip ring pairs must be dedicated for TTL to 24 VDC triggers

HD-SDI or NTSC video signals must be fed through slip rings

3.0 MILESTONES

The Contractor shall deliver three (3) tracking mounts no later than 365 days after receipt of award.

4.0 DELIVERABLES

The contractor shall deliver all hardware and documentation to 704 TSS/XPL at 1644 Vandergrift Road, Building 1260, Holloman Air Force Base, New Mexico 88330-7850.
