Topics • Sites • OSU • Wright-Patterson AFB (near Dayton, OH) • Eglin AFB (near Fort Walton Beach, FL) • Logistics • Deployment • Packaging • Shipping • Sustainment • Emplacement
Local Sites: OSU Don Scott Airport • Area available for experimentation: 1km x .5km • Has significant background noise & wind • Has significant plane traffic • Learned that acoustic sensors hear planes well • Learned that microphones are sensitive to temperature too (Tuesday pm temp: <40ºF) • More about Williams Road Warehouse site later in IPT testsite testsite
WPAFB NEST Site(WPAFB Laser Test Range) Can accommodate 1km x .5km experiment Approximate Fence Line ~0.5 km ~3 km = potential site for tent, NEST control cell, and IPT viewing area
Logistics • Experiment Execution • Large monitor for IPT day • Two-way radios (4 total) • GPS device • Set of binoculars • Large storage container (with lock) for locking up monitor and other valuable items each night • Truck for moving sensors from warehouse to site, distributing sensors, hauling food/water, etc. • ATV for testing • Soldier with weapon for testing • Some flags/cones for marking boundaries of sensor field • We may want to film some of the effort, so a video camera may be needed • Tent (large – maybe 20’ x 40’) with sides that can fold down during rain and roll up during hot/clear weather • Tent stakes: normal stakes for part of tent near grassy area, special stakes (or something similar) for penetrating hardstand material. • Large hammer for stakes • Lights for hanging inside tent • Large industrial fan for blowing air into tent • Tables (6’ in length): at least 5 • Folding Chairs: at least 12 during normal work days (maybe more for IPT day) • If not set up on hardstand, then may need plywood to place under chairs and tables
Logistics(continued) • Power • Access to electrical power • Extension cords/power strips • Car battery chargers for charging Tier 2 batteries • Generators (at least 2) – as backup (for power access above) or for primary power [NOTE: Size of generator should accommodate laptops, monitor, lights, fan, and car battery chargers • Fuel for generators • Fuel storage container • Food/Refreshments • Two large coolers for ice and drinks • Two water jugs for ice water • Food (lunch? Other?) • Paper plates, paper towels, paper cups, plastic ware, etc. • Other • Garbage bags • First aid kit • Portable toilets (extra toilet paper) • A heater (with fuel) for October test/experiment period • Access to solder equipment for repairing sensors • Mowing grass
Logistics(continued) • Tier-2 Sensors • Total Weight of 300 Tier-2 batteries • Will tier-2 batteries create a storage problem (hazardous material) • Tier-2 batteries must be completely sealed to prevent environmental hazards, safety issues, and storage issues • Tier-2 batteries have to come fully charged. • Warehouse • Need warehouse for storage of sensors and batteries when they are shipped to WPAFB • Need a shipping address for the warehouse • Test/experiment site is primarily thick grass. Grass should be mowed just before each test/experiment period and NOT mowed once the sensors are set up • Should establish procedure for use of on-post/off-post medical facilities for emergency and non-emergency use • Since a WPAFB person needs to be with NEST personnel at all times, a schedule should be set up to accommodate working other than normal working hours (e.g., working from 7:00 AM to 8:00 PM) • Will need access to high speed internet (e.g., Bill’s office) for downloading/uploading NEST programs/information • Crossbow shipping containers should require no more than two people for lifting/handling
Final experiment site: Eglin AFB, Florida Eglin AFB is located in Northwest Florida; often associated with Valparaiso, FL. Neighboring cites include: Niceville, Shalimar, Fort Walton Beach
Final experiment site: Eglin AFB, Florida 300’ Tower View West from Tower View East from Tower
Final experiment site: Eglin AFB, Florida • Considerations: • Environmental Impact • sea turtle nests • birds, if not birdnests • Sea grass • Buildings/built-up areas • Dunes & Swampy areas (a few) • Wind, rain Fence on West End Work Area
Dense Sensor Field Sensor Area Simple Example of Experiment Approach
Access to Site • Airports • Okaloosa Regional Airport is on State Road 85, on Eglin AFB • Pensacola Airport is on Airport Road in Pensacola, about 60 miles from Eglin AFB • Hotels • Many “off-season” accommodations in Fort Walton Beach and nearby Niceville, Destin, and San Destin (site of next PI meeting) • Fort Walton Beach hotels are within a couple of miles of gate on east end of experiment site
DeploymentXSM Packaging 12+ in • Package 41 XSMs in container slightly > 1 cu ft • Total: 244 boxes • 244 cubic feet = 7’ long x 7’ wide x 5’ high • Weight Box: 41 x 200g = ~ 18 lb (~20 lb with package material) Total: ~ 4880 lb • Considerations • Packaging should be sturdy enough to be stacked at least 5’ high • Packaging should be sturdy enough to be reusable 12+ in Bottom & Top Layers Middle Layer Spacing material a little wider than the antenna diameter 12+ in Side View
DeploymentShipping Considerations • Volume and weight of XSM packages • Weight: 4880 lb • Volume: 244 cu ft • Packaging for stargates and tripods • Stargate batteries • 300 x 35 lb/battery = 10,500 lb = 5+ tons • Volume: ? • Back-up XSM batteries • 10,000 AA batteries @ ~2 oz/battery = 20,000 oz = 1250 lb • Volume: ? • Consider: • NEST 18-wheeler
DeploymentSustainment • Recharge Stargate batteries • 300 batteries x ~2 hrs/battery = 600 hrs • 1 charged at a time (8 hrs/day = 5/day) = 60 days • 5 charged at a time (8 hrs/day = 25/day) = 12 days • 10 charged at a time (8 hrs/day = 50/day) = 6 days • Replace XSM batteries • Take out 4 screws, replace batteries, and replace screws • By hand* = 10 min/XSM • 100,000 min = 1667 man-hours = 208 man-days (@ 8 hrs/day) • With power screwdriver = 2 min/XSM • 20,000 min = 334 man-hours = 42 man-days (@ 8 hrs/day) * Assumes no hand blisters, no carpal tunnel syndrome, no complaints, no breaks
DeploymentXSM Emplacement 4 rows @ 1,000 sensors/row 10 m 10 km 10 m 40 m 20 m 20 m 8 rows @ 500 sensors/row 160 m = 4,000 sensors (4 rows @ 1,000 per row) = 4,000 sensors (8 rows @ 500 per row) Not to scale
Calculations for XSM Emplacement 10 m Section (~3.3 hrs for 4,000 XSMs) Time to walk 10 m at 3 mph (fast in sand = 1.33 m/s) = 7.5 sec Time to pull antenna and set down one sensor = 2.0 sec Total time 10 seconds For one person to place one row = 1,000 at 10 sec = 2.8 hours Assume 4 distributors for this section and 4 ATVs w/drivers Assume the person can carry 41 sensors. So after every 41 sensors, it will take about 20 seconds to walk to the ATV and pick up 41 more sensors and return to the next sensor drop point So add another 20 seconds x 25 stops = 500 seconds = 0.15 hours Assume the ATVs (4) can carry enough sensors for at least half the entire run [500 sensors = 13 boxes] Assume 20 minutes for resupply Total Time: ~3.3 hours Issue: How to deal with packaging material
Calculations for XSM Emplacement 20 m Section (~2.5 hrs for 4,000 XSMs) Time to walk 20 m at 3 mph (fast in sand = 1.33 m/s) = 15 sec Time to pull antenna and set down one sensor = 2.0 sec Total time 17 seconds For one person to place one row = 500 at 17 sec = 2.4 hours Assume 8 distributors for this section and 4 ATVs w/drivers Assume the person can carry 41 sensors. So after every 41 sensors, it will take about 20 seconds to walk to the ATV and pick up 41 more sensors and return to the next sensor drop point So add another 20 seconds x 13 stops = 260 seconds = 0.07 hours Assume no ATV resupply Total Time: ~2.5 hours Issue: How to deal with packaging material
Calculations for Stargate Emplacement Stargates (~4.3 hrs for 300 Stargates) • Set-up • 2 min/Stargate x 300 Stargates = 600 min = 10 hours • Unload Stargate, battery, tripod • Set up tripod • Connect tripod to Stargate; and Stargate to the battery • Check GPS location • Assume 4 ATVs (2 people/ATV) working at once 2.5 hrs • Drive from point to point • ~150 m between points • 15 mph (6.7 m/s) ~23 sec per point • 23 sec x 75 Stargates (for one ATV) = ~ 0.5 hr • Drive back to get more Stargates/batteries • 20 Stargates/ATV • 20 min/run x 4 runs = 80 minutes ~ 1.3 hr Total Time: 5.3 hrs
Time for Emplacement/Collection • Emplacement • XSMs: 10m: 8.25 hrs • XSMs: 20m: 6.25 hrs • Stargates: 4.3 hrs • Collection • Will take more time • To dry off/clean XSMs, Stargates, tripods, and lead-acid batteries • To deal with packaging
Emplacement Issues • Topology • OSU distribution • Uniformed distribution in three belts (10m, 15m, 20m spacing) • Random (e.g., overlapping elliptical patterns that simulate release from artillery shells) • Time for Stargates • Shipping/storing batteries • Charging batteries • Emplacement/Collection on rain days • Need to train personnel • Optimum emplacement • Procedures • Time to check status of motes each morning
