    GPS Cutaway Tracking

    The subscription model can bee moot if you also make a "Remote area base receiver" like a mobile cell tower that works for ~1mile. This way, a dropzone that has a bunch of people and difficult area of operation can buy a base station for everyone who jumps there. No yearly cost for network, no sim cards no ransom-ware fees. I built a similar thing a few years ago with an RFID sticker and a long range pinger. The maximum range I got was only 50 feet so it is useless for skydiving but OK for finding things around the yard. Rough maximum size should be about the size of a golf ball. Just for reference: the main canopy activation handle comes in various sizes but most of them are hacky sacks. I think that the size and weight will matter less if we attach it to the deployment bag or the canopy directly. It would be more critical for attaching to risers. This size should work for general rig and helmet inventory tracking purposes. There are no dangerous dives Only dangerous divers

    GPS Cutaway Tracking

    Chris, Some skydiving locations have spotty reception and this is exacerbated by trees, ponds, rocks... The $60/year charge is a bitter pill to swallow. Is there a way to do a "pay per use" model. Like: you just pay for the tracker then only if you lose your canopy, pay $20 for the pinging to work? Installing in the pilot chute was my first thought too. Take a look here:http://www.chutingstar.com/media/catalog/product/cache/1/image/1200x/040ec09b1e35df139433887a97daa66f/m/i/miragehandles_1.jpg The little ball is the activation handle for the main canopy. it is the size of a hacky sack. But you probably can attach it anywhere on the canopy (Dbag, risers, slider... these are all places that the skydivers here know). If this can send 600 pings per charge and only turns on after the cutaway happens than there should be no problem to charge once a month, keep it passive until the cutaway. Even if it just sends one ping once it lands with GPS coordinates accurate to 50 feet...then this is a good thing. What I would like to see is a tracker that is permanently attached. I charge it once a month or just make sure it is charged before I jump. (so even if it is inside the packjob, I am fine). The tracker can be totally passive for hundreds of jumps. If there is a cutaway then it turns on and sends pings once a minute until it stops moving. Then one ping each 10 minutes for 24 hours then once an hour until it dies. The ping can go to a website with GPS coordinates. You only pay to access the website without a yearly subscription. Just to give you some perspective about frequency of occurrence. The average cutaway frequency is once every 700 jumps (Not trying to start an argument just giving the guy some idea...). Some skydivers will not cut away in several years. Paying 60$/year is a bit harsh especially if I buy 2 or 3 of these things. There are no dangerous dives Only dangerous divers

    GPS Cutaway Tracking

    Hello Chris, Welcome to the wonderful world of skydiving. I would like to help you better serve the skydiving community. (Disclaimer: I am a malicious idiot who might have no clue what I am talking about...Be warned!) There are a few things that a small GPS tracker can help with in our sport. 1) Find main canopies that have been cut away: A main canopy costs anywhere between $800-$2,000. Sometimes a skydiver may decide to release the main canopy and attempt to land a reserve canopy. This can happen at at many points in the skydive. The released canopy will then be carried by the wind and land wherever it lands. If the canopy can be recovered and reattached then the skydiver does not need to buy a new canopy. Skydiving usually takes place in rural areas that may have trees or farmland around (Bad network signal). A canopy that falls in to a corn field could be invisible to a low flying plane and in some occasions they get completely lost. For this scenario, there is no need to track the main canopy until it is separated from the parachute container system. Once it is separated from the system then a ping every 1-10 minutes would be nice. 2) Cutaway + reserve handles and freebag The process of detaching a malfunctioning main canopy from a parachute container system involves pulling a "cutaway" handle. This handle ($60 minimum) can get lost during the process since the person's hands may need to pull the handle and then do something else. Students are routinely taught to ditch this handle after activation. Without the cutaway handle, the parachute system (AKA: Rig) can't be used. The skydiver would need to procure a replacement before being able to jump. The reserve handle ($90) has a similar procedure but the reserve packing is regulated and the associated handle has certain requirements. The freebag ($250) is a deployment aid for the reserve canopy. During a Cutaway, the freebag will detach from the system and land on it's own. They are also only packed by a licenced rigger and it can be difficult to legally add a tracker to them. 3) Stolen rigs and general inventory management Several rigs ($3,500-$8,000) get stolen each year. They look like backpacks sitting in a car. Some skydivers (and teams) have multiple canopies and rigs and sometimes the only way to know what is packed in a rig is to open it up. Skydiving schools or rental shops also need to manage their gear inventory. Even skydiving helmets ($300-$600) have a tendency to get lost. Some helmets have cameras and other gadgets on them that can drive the price even higher. Some operational considerations: The average skydiver jumps ~100 times a year. The tracker can't be charged after every jump. The main canopy can be disassembled, packed and accessed by the skydiver unlike the reserve that most people will only ever access once in 6 months. I think that 600 pings per charge is a better metric than usage time. Bluetooth connection is nice but some people do not jump with their super expensive smartphones. What is the range on your tracker signal? Attachment: don't worry about that too much. Make it small and give us the ability to sew, glue, ziptie or whatever it to stuff. The closest GPS tracker I can think of is the Flysight system. There are no dangerous dives Only dangerous divers

    iFly pricing and other stuff

    Disclaimer: I don't work for iFly and generally don't know what I am talking about. Pricing: About two years ago I bought bulk time at iFly Loudoun at the pre-opening rate of $860/hr. I have been using up that time in 10-15 minute increments since they opened. This weekend I used up the last few minutes on that account and inquired about adding more time. The bulk account rate is $1,000/hr ($16.67/min). I and my "team" can use it as long as the names are on the account. I can't bring a random coworker or even a family member. There is a return flyer rate that goes for $160 for 10 minutes and includes coaching and you can bring up to five people. You have to use it at 10 minute increments. You can't use more that 20 minutes in a single "block". There is a "standby" flyer rate of $12.50/min but it does not say that you have to buy a bunch of it in advance. I am not sure I understand how the terms of payment work. The flying looks simple: show up and fly what ever time they can give you on the spot? I also know that there are some coaches/instructors that buy really large blocks of time. You get coaching with them that includes the tunnel time at their low rate. Other stuff: iFly just recently changed the way they talk about arrival time and flight time. When you call iFly now, the time you are given is arrival time and NOT flight time. The staff will tell you to be there at 10 for flight time at 11. The whole idea of "Blocks" is funny in the newer tunnels with the doors that can open and close while the tunnel is running. For first timers it make sense but for us it is very fungible. This brings me back to those 10 minute blocks with coaching for $160. If you get 3 blocks, you can book 20 minutes in one "block" and 10 minutes in the next "block" so you can effectively get 30 minutes for up to 15 flyers. SO the whole "Block" idea is nice for the instructors and staff to plan their day but the flyers should arrange their own way around this. If I am missing some point here, please let me know. I don't write this for your benefit, I write this to get the correct information so please help if you can There are no dangerous dives Only dangerous divers
