The largest installation of NASA: the Marshall Space Flight Center They sneak into a Russian base and there record two abandoned space shuttles A Spectacular 360º Video that Takes You to Space as the First Polish Cosmonaut For example, what if the bike tracking system could be applied by using Estimote beacons to track the location of objects in microgravity, aboard the International Space Station? The concept of contextual computing and its potential to revolutionize hardware and software mechanics can enable engineers at NASA to attack problems from entirely new perspectives.Among the many things you can do with the famous Google maps application is to observe from the air the impressive facilities of the US space agency, NASA. He’s already brainstorming new ways to integrate BLE tech and Estimote beacons in space exploration. Plus, we’re hearing all sorts of ideas! David is a self admitted Estimote enthusiast. Well, what good is a foot in the door at NASA? We can’t help but humblebrag about influencing a NASA intern, ourselves. Often you hear in business that a foot in the door is everything. Estimote has done a fantastic job on this end!” - David Lie-Tjauw, lead project developer Often times, the biggest barrier that keeps users from implementing any new technology is the availability of help and resources needed to figure out how to use such technology in the first place. I would like to give a shout out to Estimote’s amazing engineers and developer community who have created extremely useful and comprehensive documentation for the Estimote SDK. “Bike tracking at NASA JSC would not be possible without the use of the Estimote SDK. In order to successfully run Android applications on the Raspberry Pi, David used Android Things, a brand of Android OS specifically tailored for the Internet Of Things. Most of our developers use smartphones, but it was clear off the bat that smartphones wouldn’t scale for this project… the campus is huge! Needing a smartphone for every building would be expensive and battery life would be killer, so David utilized Raspberry Pi’s, mini barebones computers with no screens to work alongside Estimote SDK. NASA employees can use this website to find nearby bikes. As bikes move throughout campus, the website will update in real-time to accurately display the number of available bikes at specific buildings. Finally, an easy-to-use website called BikeJSC reads the bike data from Firebase and visualizes it on a Google Map image of Johnson Space Center. The Raspberry Pi updates the database roughly every 30 seconds, so once a bike leaves a building, the Firebase database will reflect changes with each update. For example, a Raspberry Pi in Teague Auditorium would tell Firebase that bikes #12345, #54321, and #19283 are at Teague. When a bike is parked at a building, the Raspberry Pi and Android app sees the beacon identifier, sending it to the online real-time database (in this case, they’re using Google Firebase). Stationed in every building at JSC is a Raspberry Pi, substituted for a smartphone, hard-coded with a permanent location tag and running a custom-built Android application that scans for nearby beacons. Each free-range bike is outfitted with an Estimote Proximity beacon, broadcasting the identifier of the respective bike. The problem? People had trouble actually finding them on campus! Thus, the project was born: what if employees could simply log in, and view the real-time locations of the bikes? These over 300 bikes are available for NASA personnel to freely use. After numerous brainstorming sessions, they honed in on Johnson Space Center’s free-range bike program. With the mentorship of NASA leadership, David was able to flex his technical knowledge while gaining precious insights and education to building a fully workable product. David was working alongside the sustainability team at NASA to identify issues and prototype unique solutions. It all started with a summer internship by an ambitious Computer Science student from Washington University in Saint Louis named David Lie-Tjauw. With about 3,000 employees, 12,000 contractors, and a steady stream of interns and students making their way around the facilities at any given moment, efficient modes of transportation are a must … rockets and space shuttles aren’t exactly pragmatic! Enter their bicycle sharing program, tracked and powered by Estimote beacons. NASA’s Johnson Space Center campus is always bustling with people.
