Purchase of Motion Sensors with Accessories

***The National Oceanic and Atmospheric Administration’s (NOAA), Pacific Marine Environmental Laboratory (PMEL), intends to negotiate, on a sole source basis, under authority of FAR 13.106-1(b)(1), with Inertial Labs located in Pateonian Springs, VA for motion sensors and accessories to be delivered to NOAA/PMEL, Seattle, WA

***The sole source determination is based on NOAA’s requirement that Intertial Labs is the only vendor that manufactures and distributes this specific motion sensor system. PMEL has standardized on this motion sensor. PMEL systems are designed around the use of this sensor. Using any other sensor would require considerable re-design and re-programming.

TECHNICAL SPECIFICATIONS:

The motion sensors in need must have the accuracy required for motion corrections to the precision that allows retrievals of eddy-coherence sea surface fluxes of momentum and energy when used in combination with other sensors. This requirement includes:

• Sampling frequency: > 20 Hz
• Operational range: -40 - + 70˚C
• Mean time between failures: ≥ 100,000 hrs
• Power consumption: ≤ 6 Watt
• Weight: ≤ 0.3 kg
• Range, resolution and accuracy:
