66 -- AMENDMENT 0001 VEHICLE CONTROL AND TRACKING SYSTEM REQUIREMENTS CONTRACT SOL DAAD01-98-Q-0009 DUE 030998 POC Becci Larson (520) 328-6163 WEB: blarson@yuma-emh1.army.mil, blarson@yuma-emh1.army.mil. 1. Amendment 0001 is published to provide the following answers for questions asked under Solicitation No. DAAD01-98-Q-0009: Question (Q) 1: Paragraph 2.1.1. In our system, velocity (speedometer reading) is provided in real time along the direction of travel. Also (ref. SOW 2.2.2), X and Y positions are provided in real time as latitude & longitude. X and Y components of the velocity can be readily obtained for the speed and direction pairs during post mission processing. Is this acceptable? Answer (A) 1: No. Although the real time speedometer reading is needed as one of the base station display parameters, USAYPG also needs actual position and velocity provided as output for real time monitoring and control of the entire test mission. Q.2: Both paragraphs 2.1.1 and 2.1.6 ask for Z dimension data which is altitude or elevation. Our system is designed for use with vehicles moving on the ground and does not provide elevation data for velocity or height. Is it acceptable to obtain elevation data by plotting the path of the vehicle on a topographical map with elevation resolved? A.2: No. Elevation output is also needed. USAYPG Digital terrain elevation maps are incomplete and those available typically do not have the resolutions that are needed to derive accurate Z measurements in elevation. Q.3: Paragraph 2.1.4. We will time stamp the data to 100 microseconds resolution with the following observation. The requirement for time data to be stamped to 100 microseconds resolution appears needless. This provides data stamped at 0.11 centimeter resolution at 40 kph and the system resolution is only 20 cm, which is reported once a second. Time stamping of data to 5 or 10 milliseconds is more realistic. Time stamping the data at 100 microseconds time resolution does not imply position accuracy of 0.11 centimeters. A.3: Agree. Time stamp accuracy is not intended to infer position or velocity accuracy. Accuracy is desired for correlation with other test data that is also time stamped. Q.4: NOTE: The words "disable" and "abort" have specific meanings to us and the word "disable" appears to have two meanings in the SOW. For example: Q.4A: Paragraph 2.2.3. If disabled (aborted for a dangerous situation) the vehicle must be physically visited and reset for safety issues. If paused (engine running and brake on), the vehicles can be resumed (start moving again) at any time the base station operator desires. While paused, detours can be changed by the operator inputting way points from the control computer at the base station. Is paused the desired action? A.4A: The desired action is a capability(s) that allows the operator to: a) Rapidly stop and shut off (abort) any combination of vehicles; b) Remotely re-start and operate any combination of vehicles; and c) Manually initiate and/or change a preprogrammed detour path from passing on one side to passing on the other side. Q.4B: Paragraph 2.2.4. Does "Shut-down" mean pause so the vehicle can resume movement soon thereafter. Advise if the comment is intended to mean a shut downat the end of the work-day or test sequence so the vehicle can be remote started the next time it is used. A.4B: The intent is that: a) Within 2 seconds of the operator's (abort) command, the vehicle will have its brakes fully applied. In addition, after the vehicle has stopped, the brakes should stay applied and the engine halted; and b) Within 15 seconds of the operators re-start command, the vehicle's engine will be ready to start and the starting system will attempt to start the engine. Q.5: Paragraph 2.3.4. Does "re-start" mean after engine is turned off? Or does it mean move again after a pause (a normal operation)? A.5: Re-start is intended to mean re-start a stopped or stalled engine. Q.6: Paragraph 7.2.1. Does "disable" mean pause and resume (see 2.2.4)? Pause and resume is a normal operation. If disable means abort, then an operator is required to access the vehicle and reset to clear a dangerous situation (2.1.5) which required an abort disabling the vehicle. Is this acceptable? Is this a safety issue? A.6: The intent is to: a) Rapidly stop and shut off (abort) any combination of vehicles; and b) Remotely re-start and operate any combination of vehicles. Safety is a primary reason for remote re-start. Live ammunition near vehicle(s) will prohibit approach of an operator for system reset. Q.7: Paragraph 7.2.2. Does "disabled" mean aborted (no longer able to operate)? A.7: Yes. Q.8: Paragraph 7.2.3. Does "disabled" mean aborted (no longer able to operate)? A.8: Yes. Q.9: Paragraph 7.2.5. If echelon implies parallel movement, please give an example of non-parallel movement. A.9: Example: Vehicles moving in the same general direction at approximately uniform speeds on independent paths that vary somewhat from parallel (normally to avoid obstacles). Q.10. Do we assume that the antenna tower is not part of our proposal to the Governement? A.10: The antenna and any necessary stand, brackets, or tower should be considered part of your proposal in order to deliver a complete system. Note that the base station needs to be designed to allow setup, supervision, control, and tear-down by a single operator. As a result, an extremely large or permanent antenna tower is unlikely to satisfy this requirement. Q.12: Can we assume that the area is safe for operation or should the proposed system take into account the presence of known dangers? A.12: The operating area is not safe. The system as delivered shall be designed to enable USAYPG to store any desired vehicle route (way points). This programming shall permit the system to be taught the desired, traversable routes for the controlled vehicles. With a system properly guiding the vehicles within their programmed paths, obstacles and hazards should not cause a problem because only safe routes will be programmed for the vehicles to follow. In actual operation, under system control, the vehicles will be unmanned and will typically be used as live fire targets. Driver or personnel safety is not a concern under these conditions. Note that drivers must still be able to safely control vehicles for normal movements (stage vehicles to prepare for operations) even after kits are installed. 2. Pursuant to the above, the closing date for receipt of Proposals is extended to NLT 5:00 PM, MST on 9 MARCH 1998. (0054)
