Description
THIS NOTICE CONSTITUTES AMENDMENT NO. 2 TO THE COMBINED SYNOPSIS/RFQ FOR ENVIRONMENTAL COMPLIANCE AND OPERATIONS-ECO. Companies shall acknowledge all amendment(s) in their quote. This notice serves as the official amendment to subject synopsis/RFQ and a written amendment will not be issued. The purpose of this amendment is to answer the following technical questions submitted: Question #1: Is the the Gyro Bias Performance specified as <1 deg/hr (long term scale) for an ambient condition or over a temperature range. If over temperature, what is the operating temperature range required, how fast (slew rate) is temperature expected to change over that range? Answer #1: The gyro is to be operated primarily in Texas and Florida with operations beginning in the early morning and terminating by late afternoon. Therefore, the ambient temperature conditions could vary from 50F-80F in the cold season and 80F-110F in the summer over the course of 8 hours. Question #2: Sensor bandwidth is specified at >300Hz. Is this defined as a gain (-3db) or phase (-90 degrees) requirement? Is the same specified bandwidth required for both the gyros and the accelerometers? Answer #2: Sensor bandwidth was specified to provide an oversampling of our navigation integration rate of 50 Hz such that a data dropout would be a limited quanta of information loss. If high reliability of data transfer at rates of 50Hz can be demonstrated, we could consider relaxing this requirement. It is required that both the gyros and accelerometers report out at the same rate. Question #3: What is the dynamics range requirements for the sensors? Specially, what is the gyro rate range requirement in degrees/second and what is the capture range for the accels in G's? Answer #3: The body rates nominally will be less than 25 deg/s but some off nominal conditions may be up to 50 deg/s. The nominal acceleration capture range is less than 3 G's but some events may have transients up to 10 G's (I.e. A hard abort under tethered flight). Degraded acceleration capture above 3 G's could be an option. Question #4: Can you provide more specific vibration (flat random or sine on random) and shock operating profiles that the IMU will be potentially subjected to? Answer #4: This answer may be viewed at: http://procurement.jsc.nasa.gov/NNJ12444591Q/Answer-4.docx The due date for receipt of offers is extended to September 18, 2012. Companies shall provide the information stated in the synopsis/RFQ posted on the NASA Acquisition Internet Service (NAIS) on August 16, 2012. Documents related to this procurement are available over the Internet. These documents reside on a World Wide Web (WWW) server which may be accessed using a WWW browser application.
