Abstract:Resupply by airdropping or drone-shipping is a new resupply strategy in backpacking. In preparation for reconnaissance in long distance backpacking and SAR activities in remote areas, with little or no development, we consider the use of amateur radio with GPS beacons for resupply trackingand geo-tagging. While 6G communications using GPS satellites are available for mountaineering beacons, we use a dual strategy with an additional amateur radio based AX.25 packet radio using the PSAT based cubesat for publishing location information.Additionally, two cargo iTag locating satellites, bot cubesats are also used for iTag location and the automatic publication of tag locations on geocaching.com. The satellites are AENEAS and PTecSAT.A logistics exercise is introduced, proposed to be conducted at Uncas Scientific Area, near Big Lake, MN, with an operations logistik for the spanning of drop locations and radio fox hunt, using a reconnaissance track, mobile cache device.Keywords: iTag, iBeacon, AMSAT, cubesat, AENEAS, PTecSAT, 6G, AX.25, resupply, mountaineering and backpacking, SAR.What: The AMSAT AENEAS(“Technical Details for Satellite AENEAS” n.d.), PTecSAT(“IARU Sat Coordinator” n.d.) satellite is used for resupply iBeacon tracking, with a payload of water sachets and soylent coffee packs, for mountaineering resupply logistics. Radio Fox Hunting combined with alpining is defined as a newer, ultralight backpacking technique.How:iBeacons, defining 100msec bursts at 2.425GHz are designed with the minimum wattage needed for detection on the field by the AENEAS satellite. 100 such packages containing 1-liter pouches of potable water and three meals of soylent of 87 grams each. This proof of concept study is to be conducted at Uncas Dunes Scientific and Natural Area (SNA), with an area of 658.3 acres , we have a density of airdropping of 6.58 acres per package, leading to an average distance of 26628.32 square meters, by pi/4 d^2, d is 184 meters in circle close packing model.We determine an optimal trajectory for the radio fox hunt over a published geotag distribution of 100 resupply caches.Why:Resupply strategies, form an important role in long distance mountaineering and backpacking missions, for wilderness areas with little or no little development, for example the pacific crest trail, in the united states, a strong resupply strategy along with an armada of reconnaissance track mobile caches are needed for effective mountaineering and/or search and rescue operations, with a resilience plan for extreme weather operations.The use of 6G like simulated communication is possible by using better encryption and packet compression over a slower AX.25 network, with the use of A.I based technologies like image cartoonization and feature representation and speech to text conversion for lower bandwidth requirements.So What:The use of reconnaissance tracks, along with airdropped resupply, will improve the efficiency and quality of mountaineering and provide vital air support for search and rescue operations. Resupply beacons also provide supplies for hikers or backpackers lost in the wilderness and also provide emergency communication hotspots as the beacons are still active to transreceiver emergency messages.Summary:Main Points:6G network using cubesats, PSAT NO - 84, AENEAS, PTecSATOperation Logistics for a proposed resupply air dropping over Uncas Scientific Area in MN.Algorithms for the automated resupply from caches using an autopilot based track mobile cache.Applications: tele-medicine, 360 photography.
