OLHZN-10 is the tenth planned high altitude weather balloon flight for Overlook Horizon High Altitude Balloons. This flight is scheduled for late-March to mid-April 2018. The focus of this flight will be to test our updated radio tracking systems to ensure that our repairs we made after last year’s flights are performing as expected. This flight is expected to use three Lightdow LD4000 Cameras including one upwards facing camera recording the balloon burst.
This flight will again feature three Lightdow LD4000 Cameras including one as an upwards facing balloon camera to try to capture the balloon burst event. We have made numerous changes to our main tracking system over the winter including both hardware and software changes. We’ve also added a watchdog reset timer to our software that will allow the system to intentionally reboot itself mid-flight if the system should freeze mid-flight like it did on our last flight, OLHZN-9.
We’ve developed a new miniature tracking system that we’ll be testing on this flight in addition to our main tracking system. This additional Arduino Pro Mini will give us additional redundancy and allow us to test a smaller platform that will eventually fly on its own.
