Innovative High-Altitude Balloon Project: LOHAN
Ground Control is spearheading the LOHAN initiative, which focuses on deploying a glider via a high-altitude balloon. This enterprising project involves releasing the glider at the fringes of space, allowing it to autonomously navigate back to a predetermined landing area. However, effective dialog is crucial for the success of this mission.
Communication Challenges and Solutions
In the event of losing GPRS connectivity, the LOHAN team would face notable challenges in maintaining contact with the glider. This lack of communication could hinder emergency procedures, such as the need to cut the balloon loose if it veers off its intended path, potentially complicating the situation for authorities.
RockBLOCK: A Reliable Communication Tool
in their comprehensive article, Ground Control details how the RockBLOCK device can transmit GPS information even when standard mobile networks are unavailable. This technology leverages Iridium’s global satellite network, ensuring that the team can send commands from the ground. This capability allows for mission aborts or self-destruction protocols to be executed via their API.
Key Components of the LOHAN Project
- RockBLOCK naked unit
- arduino Mini Pro 3.3V 8MHz
- 5V voltage regulator
- AAA battery holder
- Four Energizer lithium AA batteries
- MOSFET for release activation
- Cable with JST connector for cut-down mechanism
- The LOHAN Spacecraft
Mission Overview
The team intends to launch a rocket-powered Vulture 2 spaceplane from beneath a helium balloon, with the goal of having it autonomously return to Earth using an onboard autopilot system.
