HASP Launch

Take a look at this new press video highlighting the launch of the 2012 HASP Balloon featuring ASU’s HATS payload.  Throughout the flight all systems were nominal and data is forthcoming.  Thanks to all those you supported the project and worked hard to make this amazing flight possible. -Patrick McGarey // Project Lead

Thermal Vacuum Test

Inside the Thermal Vac

Earlier this month, the HATS team took the newly completed payload to Palestine, TX in order to integrate with the larger HASP platform.  During this visit the payload was attached to the HASP platform and two thermal vacuum tests were performed.  The payload experienced a stressed environment where pressure ranged from 1000mBar (atmospheric) to 5mBar (float) and -50C to +50C.  These tests were performed at the Columbia Scientific Balloon Facility (CSBF) located just outside of Palestine, TX.  We were relieved that the system survived both tests and are excited to be apart of the actual flight later this month.

Completed HATS Payload

HATS Payload

After months of design changes and managing subsystem integration issues, the final payload is completed and ready for testing in Palestine, TX.  The HATS payload will be integrated with the larger HASP platform and thermal vacuum tests will be conducted. After these tests, small scale changes to the payload may be necessary but the system as designed will not be altered.

Boxed In

Electronics Update: There is a lot going on inside there. From Openlog SD card writers to DC-DC power regulators, the interior components of this box have been hand wired and routed through circuit boards, also soldered in house, in order to handle the diverse amount of measurements which the HATS payload is capable of.

Hardwiring HATS

Back of Circuit Board

With much of the initial electrical prototyping complete, the HATS electrical system was rebuilt from the ground up in a more reliable and durable manner.  The major circuit components were reduced for size and efficiency and a main sensor routing board was completed. (board shown above partially soldered)

HATS Concept Demo

The ASU HATS (High Altitude Turbine Survey) payload, which will fly in September 2012 abord the HASP (High Altitude Student Platform), is shown demonstrating some of it’s basic operations.  Those operations include running all onboard sensors simultaneously, while collecting data using an Arduino Mega.  This demo was required by the School of Earth and Space Exportation Senior Design class.

Desktop Demo

While the HATS team continues to test and calibrate individual sensors, it is also important to understand how the entire array of senors, motors, etc, will operate as a complete system.  This is where interfaces and electrical know how become very important.  The above picture is a desktop demo showing the exposed electronics that will eventually find a more defined home within the HATS payload.  Pictured above in no particular order are…2 motors with optical sensenors, 3 wind speed detectors, 5 pressure sensors, 4 temperature sensors, 2 Arduino Uno boards, voltage regulator, power supply switch, and a LiPoly backup battery.  The AIRMAR Weatherstation and strain gauges are not shown.

Machining

Over spring break, the HATS build team decided to fabricate the aluminum electronics box.  The material for the box was milled, tapped, and completely test assembled all within 4 hours.  The next step will be mounting electronics hardware within the box.
