- Description
- This amendment is issued to provide answers/questions and is provided as amendment 0001 to the Synopsis (W9124R-07-R-0013). 1. Are there any restricted or reserved RF frequencies being utilized that would limit the frequency selection of the potential vendor? A: All wireless communication links must operate in compliance with Federal radio bands. This requires obtaining a JF-12 number processed on Department of Defense form DD 1494, Application for Spectrum Review. System compliance with Federal radio bands is the sole responsibility of the contractor, as stated on sections 1.2.2, 1.3.6 and 3.1.4 of this statement of work. 2. What is the size and shape of the typical volumetric impact field? (x, y, z) A: 3.1 The contractor shall meet or exceed the following requirements/tasks: 3.1.1 Performance/Accuracy The system shall operate on the following: Volumetric impact fields, along line of projectiles' flight, that range from minimum .1km in width X .1km in length X 1.6km in height to maximum 1.6km in width X 6.4km in length X 1.6km in height. Surface impact fields, along line of projectiles' flight, that range from minimum 0.1km square to maximum 1.6km x 6.4km rectangle. 3. What environmental issues would place limitations to access for installing system components in or around a typical volumetric impact field by surface transport? (i.e. presence of live ordinance; un-navigable terrain, security requirements, etc.) A: Refer to section 3.1.2 for environmental requirement. Also, the presence of unaccounted live ordinance on the surface or below the surface of impact fields is real and will restrict the use of 100% mechanized surface transportation in some areas. 3.1.2 Environmental Performance. Testing areas are located in desert, (Yuma Test Center YTC at YPG), arctic (Cold Regions Test Center, CRTC, Ft Greely Alaska ) and tropical areas(Tropic Test Center, TTC). These testing areas have limited roads, no roads nor improvements and include surface conditions of almost any type, sand, snow, shallow water and gravel. Systems shall be capable of emplacement and transport in these environments. Systems shall be capable of day and night operation during clear, rain, and snow conditions. Field units shall be rugged and capable of operating in desert (50C, full sunshine, low and high humidity, and rain), arctic (-40C, rain and snow), tropic (rain & high humidity) conditions. Electronics shall be sealed against dust, water, rain, and insect/rodent intrusion. Units must be operational in winds for 1 to 10 m/s and capable of withstanding higher winds without damage. Sensor systems placed on/near impact fields shall withstand the blast wave from nearby explosive events, (41 kpa (7 psi) which is produced by 1 pound of high explosives (HE) at 10 feet, or higher amounts at greater distances). System shall continue to operate normally during lesser nearby explosive events (with the transmitted acoustic signal level at its upper limit). Base units (recording, acquisition, computer display, etc) shall be located in an Instrumentation Shelter. The instrumentation shelter is provided by the Government. However, that shelter is exposed to high intensity impulse noise (7kpa, 1psi) from gunfire or explosions. These units shall be capable of withstanding shock. Units shall be capable of operating without interruption during these shocks. 4. What is the operational concept for the use of this system: single installation and continuous use/on-off use; redeploy and energize as needed? A: Redeploy and energize as in 3.1.2, 3.1.3 and 3.1.4: 3.1.2 Environmental Performance. 3.1.3 Operational Power and Time. All field units shall be capable of 48-hour continuous operation plus a 4-day standby period. 48-hour operational and 2 week standby desired. Acoustic and other Sensor Units emplaced on/near impact field shall be self -powered. Batteries preferred. Batteries used shall be standard commercially available and easily replaced. Solar power to supplement/charge batteries is acceptable subject to the nearby explosive event survival requirement for those on impact field. Other Field Units (e.g... meteorological, wireless relays) not on impact field can use batteries or low noise generators. Definition of low noise will depend on the distance from the acoustic sensors to where these units will be emplaced. Base units (located in instrumentation shelter) shall operate on Government supplied Generator power and fixed electrical power (120 Volt, 60 Hz). 3.1.4 Wireless System Operation. Wireless communications links shall have a minimum range of 20 Km. This does not preclude the use of wireless concentrator/relay to meet the 20 km requirement. Field subsystem shall transmit subsystem status data over the wireless link to the user interface for all devices running on them. The status data will vary with the subsystem but shall include such things as battery status, wireless link radio frequency (RF) level, and self check items associated with the local devices (acoustic, meteorological, and timing). 5. Are there preferred structures for mounting acoustic sensors? A: 3.1.7 System Packaging. System instrumentation located at base control shall mount on standard 19 inch instrumentation rack (computers, hardware and displays). Acoustic Sensors shall be Portable, either by a maximum two-man carry or wheeled by one-man. Folding/Collapsing to minimize volume in storage and transit is desired. Instrumentation and subsystems which are not portable shall have some provision for transport (e.g. trailer). Also, preferably acoustic sensors shall be off-ground. 6. What resources are anticipated for installation/redeployment of field sensors? A: See 3.1.7 above for acoustic sensor portability. Mechanized transport depends on environment (desert, tropic, artic). Refer to section 3.1.2 for environmental requirement. Also, the presence of unaccounted live ordinance on the surface or below the surface of impact fields is real and will restrict the use of 100% mechanized surface transportation in some areas. 7. The system is expected to operate for a minimum of 48 hours nonstop. What is the expectation of the overall battery life ( number of active 48 hour increments plus non-active interim periods) for battery operated components? A: See 3.1.3 and 3.1.5: 3.1.5 Data Acquisition and Recording. The system shall have anti-aliasing data acquisition hardware/software to digitize and save raw acoustic data for a minimum of 48 hours nonstop sampled at a minimum of 50 KHz for each acoustic sensor module included in the array configuration (appropriate rates and data intervals for other sensors). During this time, the system shall process data and display results, plots and statistics, on multiple remote monitors while continuing to collect real-time data. At the end of each acquisition, the system shall store the data in a secure file format to prevent overwrites and to make files available for post acquisition analysis. A fault tolerant hardware controller RAID array system is preferred for local data archiving. 8. The system is expected to operate during bright and obscure light conditions. What is the expected duration of obscure light conditions and interim periods of bright light conditions between obscure light conditions? A: See answers to question 7. There is obvious day and night light conditions within the 48 hours nonstop period, plus there will be unexpected natural conditions like extreme bright sunshine, heavy clouds and dust during the day. 1.3.2 The system must serve users in numerous geographic locations, during all light conditions, in all environments and all weather conditions. 9. What GIS data is available for terrain mapping of th e typical volumetric impact fields? A: The following GIS data is in use at YPG for Government purposes and entities only.
