OKSat at Spaceport America Cup 2024

June 2024

This June, the OKSat team accompanied Oklahoma State University's Cowboy Rocketworks to the annual Spaceport America Cup at Spaceport America in Truth or Consequences, NM. This event serves as one of the largest international rocketry events with a total of 152 teams present, 66 of those being international teams. At this event, Cowboy Rocketworks aimed to fly their newest custom-wound carbon fiber rocket Arachne to a height of 30k feet. Tyler Graham, Forrest Tuschhoff, and Austin Parris of the OKSat team designed and developed Arachne's payload: a prototype of the optical receiver payload for their upcoming CubeSat mission.

The goal with this payload was to print a CubeSat compliant version of the future optical receiver payload which had previously been confined to an optical testbench setup. This prototype would be characterized in lab, flown, and then recharacterized after in an effort to gain understanding of the effects of a real launch on the payload. 

Unfortunately, due to hazardous weather conditions, Arachne was not able to fly at this event. However, the OKSat team is looking forward to launching its prototype payload with Cowboy Rocketworks this August at AIRfest 30 in Argonia KS!

Spring 2024 Senior Design Team Wins Award

May 2024

This spring, the OKSat senior design team consisting of Jacob Kay, Jacob Minick, Logan Larsh, Shawn Bejcek, and Tyler Graham has been hard at work proving that a CubeSat mission is feasible for CSLI funding this upcoming fall. This has included designing the CubeSat, proving that it has a workable power budget, ensuring it will stay within temperature parameters, simulating real-life orbits it may end up on, and developing its novel 1U optical receiver. 

At Oklahoma State University's Senior Design Expo for this spring, the OKSat team was awarded the "Best Marketing Video Award" for their promotional video, shown to the right. We can't wait to see what future senior design teams will accomplish!

Fall 2023 Senior Design Team Demonstrates Ground Station Capabilities

Nov. 2023

This fall, the OKSat team has been excited to have its first official senior design team! This team made up of ECE students Micah McCombs, Braxtyn Ackley, Eli Halcomb, and Max Wilkins set out to design and prove functionality of a ground station the OKSat team could use to communicate with existing satellites and their own CubeSat in the future. 

The team came up with a space-communications ground station capable of actively tracking spacecraft as they passed overhead. Their station consists of 2 large circularly-polarized Yagi antennas stacked horizontally with a LNA to amplify even the weakest signals coming from small sats and other spacecraft. The team successfully demonstrated the ability to remotely control the antenna and follow a real satellite across the sky as it passed overhead. Unfortunately, alignment issues prevented usable data being captured from a satellite, but a signal from a beacon in Tulsa, OK was successfully captured. 

The OKSat team is excited to continue development of the ground station and eventually permanently mount it on top of the Central Dining Services building!

Ground Station Antenna Installation 

Feb. 2023

With help from Facilities Administration at OSU (thanks to Patrick Wheeler and Billy Nash especially), the OKSat team finally got our ground station antenna derrick installed on the roof of the Central Dining Services building on the OSU campus.  Now we're working on installing the actual Yagi antenna array and snaking the cables down to our electrical receiving station inside.   We are very excited to be receiving CubeSat radio transmissions in the near future!
