SSI Overload

So you've joined [1] Slack, maybe gone to a meeting or two, but you're not sure what you can do or what there even is to do with so many teams swirling around? Well you've come to right place! Below are all the projects each team is working on, what skills they utilize or where they're especially looking for help, and who you can contact to jump in! Think of this like a jobs listing page except that the jobs are always available and you apply by poking the person of contact and saying you want the job -- and it's probably yours.

As you can see from the length of this list, there will always be more SSI to do than you will have hours in a day, week, month, or year -- don't feel pressured to overextend yourself! If you have questions, are feeling overwhelmed, or just want to chat with someone, don't hesitate to reach out to a leadership member. SSI exists for, and because of, its members (that's you.) Your sanity, health, and overall well-being always come first.

Balloons

HABMC

HABMC has a request list a mile long, but here are a couple highlights. Feel free to slack  @{{{display-name}}}  if you have ideas or questions

  • 3D visualizations using Cesium or Unity
  • Natural Language Processing for the commands module
  • Create a mobile app using React Native
  • Improved RF integrations
  • Overhaul security on websocket connections
  • Navigation algorithms

ValBal

ValBal (Valve and Ballast), is a world record-breaking high-altitude balloon payload that autonomously maintains a set altitude for days of flight by venting helium gas and dropping ballast. If you are interested in MechE, EE, CS, Physics, or even MatSci or ChemE, there's a place for you on the ValBal team!

  • MechE -- Lead: Paige Brown

ValBal's current design is a 3 part 3D printed nylon structure that uses motors to vent helium gas directly from the balloon neck, cut down the payload in the event of an emergency, and turn a wheel to dispense bb pellets as ballast from a lower compartment. The structure supports, at its heart, the avionics, which powers and control the motors and sensors. Contact  @{{{display-name}}}  if you're interested in:

    • Computer Aided Design (CAD) in SolidWorks
    • 3D printing
    • Messing with dry ice
    • Laser cutting
    • Random jank manufacturing tricks
    • and everything else that goes into making ValBal mechanics run smoothly
  • EE -- Lead: Aria Tedjarati

ValBal’s current electrical system consists of two compact, low-cost, 4 layer printed circuit boards with a custom avionics platform and a prototype digital radio communication link. The avionics consist of a multitude of sensors, a GPS, a two-way satellite communications system, motor drivers, power regulation, an embedded micro-controller, and much, much more! The digital radio system consists of a 433 MHz GFSK modulated, Reed-Solomon error corrected link that has been proven to reach ranges of 200 km at data-rates significantly greater than that of the Iridium constellation at 1/5th of the power consumption and 1/20th the cost. There are a multitude of ways to join the electrical engineering aspect of ValBal, so if any of this stuff interests you, join! Contact  @{{{display-name}}}  for more information.

  • Physics -- As a physics major, there are plenty of opportunities for you to work on ValBal. It is an insanely complex system; the flight dynamics are not yet completely understood and require simulating atmospheric and thermal effects. Good models are critical to create a good controller, another key component to ValBal that limits our possible endurance. At the same time, you can help with the design of the payload itself, considering how to optimize it for the harsh environment and coming up with good designs. Contact  @{{{display-name}}}  for more inforation and a good dose of jank.
  • MatSci/ChemE -- Lead: Paige Brown

ValBal has a fatal problem: latex balloons are quickly weakened by UV radiation and ozone at high altitudes, leading to mission ending failure in just a few days. If this sounds like an interesting problem to you, and you want to be an integral part of helping us circumnavigate the world someday, come help us figure out how to strengthen or alter the latex balloon with s c i e n c e. Contact  @{{{display-name}}}  if you're interested!


HABEES

HABEES (High Altitude Balloon Electrical Engineering Systems) is the umbrella project for all EE & CS projects outside of ValBal (that is, largely oriented at standard profile balloon launches). Because of this, there is a nearly limitless number of possibilities and projects to pursue within HABEES -- with that said, if you're new to EE or CS, or a veteran, and just generally want some ideas of what you can make, here's a bunch! Contact  @{{{display-name}}}  to discuss working on any of these!

  • HONEY EE -- the primary electronics in HABEES revolve around the HONEY architecture. If you're interested in EE, you can test circuits and/or make PCB's for this architecture and have it fly with other boards. Head over to the HONEY page to understand more about it. Below are some project ideas for circuits/boards you can make for HONEY!
    • Motor/Servo Driver
    • External/Internal Payload Heaters
    • Atmospheric Gas Sensors
    • Wind Sensors
    • SSTV Radio Board
    • WinLink Radio Email Board
    • APRS Radio Board
    • 12V Battery Management System
    • General Purpose Radio Transceiver
    • Camera Board
    • CubeSat Mapping Board
    • Literally anything else
  • HONEY CS -- although there's a lot of electronics in HABEES, they all need some software; and, even better, that software always has room for improvement, so here's some possible projects!
    • Software for tracking something (with motors/servos)
    • Improving filtering/error checking for sensors
    • Compression algorithms for logged & transmitted data
    • Enhancing speed, quality, and throughput of CAN Bus
    • Enhancing TestBench (QueenBee) test software

BUZZ is the umbrella subteam for balloons radio projects. It operated as part of HABEES, and works to develop/try/test new radio technologies within balloons. ValBal also develops independent and system-specific radio systems. Some ideas for possible projects, as well as ongoing projects, are below: Talk to  @{{{display-name}}}  and  @{{{display-name}}}  about them!

Satellites

STAR-CROSSD

The Stanford Timing And Ranging –Cross-linking Optical Small Satellite Demonstration mission is an ambitious proposal seeking to place two cubesats in low Earth orbit and establish a laser-based data link between them across hundreds of kilometers. Such a mission has never before been attempted. If successful, the technology developed will enable a dramatic leap forward in the capabilities of both cubesats and larger satellitesto communicate high volumes of data across long distances.

Optical links using lasers are capable of dramatically higher data transmission speeds than existing radio systems, but have never been successfully demonstrated at the cubesat scale. A cubesat-sized optical communications system willenable high-speed links between cubesats, allowing for networks built from affordable satellites.Miniaturizing an optical communications system to fit in a cubesat would also make it far easier for larger satellites to add optical networking capabilities, an almost essential component of proposed internet satellite constellations.

Satellites with optical links can not only transmit data faster, but also better synchronize their timekeeping with each other and measure their separation distance, important features of boththe GPS system and groups of scientific satellites. With an optical network, satellites could conduct previously impossible scientific missions and significantly improve the accuracy of GPS

Now is the perfect time to get involved with STAR-CROSSD. A number of subsystems need to be analyzed, designed, built, and tested, with opportunities to learn about electrical, mechanical, and software engineering, satellite operations, and more.

POINTR

Polar Orbiting INfrared Tracking Receiver (POINTR) has been Satellites’ primary focus since February. POINTR is an in flight demonstration of an optical receiver pointing, acquisition and tracking (PAT) system. The optical receiver payload hosted on Audacy’s 3U cubesat would be pointed to the ground to acquire and track a beacon laser sent from a suitable ground facility, currently proposed as NASA JPL’s OCTL facility. This mission would demonstrate the operational and technical requirements related to two satellites establishing an optical communications link with each other. The requirements include mission planning, command and execution of a pointing maneuver, acquisition of an incoming optical signal and tracking of the optical signal. This mission can be broken into four main goals:

  • Demonstrate a subset of technology for full bidirectional optical communications mission within the constraints placed by Audacy’s primary mission.
  • Increase chance of bidirectional optical communications mission success.
  • Develop experience within SSI designing and building space hardware.
  • Contribute to the cubesat and satellite optical communications technical fields.
