ADLER-1 is a 30x10x10 cm small cubesat, based on the SPIRE Lemur-class satellites
ADLER-1 will demonstrate that from idea to orbit it only takes 1 year.
small, but fast "bullets in the dark"
Space Debris is a problem
Decades of space activity have littered Earth’s
orbit with debris; and as the world’s space-faring nations continue to increase activities in space, so does the chance for a collision. Scientific models estimate the total number of space debris objects in Earth orbit to be more than 170 million for sizes larger than 1 mm, having impact energies comparable to a gun bullet.
It is time to get more in-orbit data on this problem.
About the project
Flying an eagle
Three remarkable partners have teamed up to fly this satellite mission: Findus Venture GmbH as a funding entity, the Austrian Space Forum as a national space research organization and Spire Global Inc., a Silicon-valley based space company operating its own fleet of satellites. The mission “ADLER-1” (Austrian Debris Detection Low Earth (orbit) Reconnoiter) is a 30x10x10 cm cubesat, based on the Spire Lemur-class satellites. Its mission is to study the (micro) space debris environment in Low Earth Orbit to complement the space debris models by obtaining in-situ data. The debris particles will be measured by an active short-range radar provided by Spire, as well as a deployable piezoelectric array provided by the OeWF.
The project has four objectives:
Spire will make their global ground station network available, including flight operations and data management, as well as procure the launch operations. The scientific data will be the bases for various research and art projects.
Austrian Particle Impact Detector
APID stands for “Austrian Particle Impact Detector” and is a 0,3 m² (tbd) piezoelectric array, where a particle impact triggers an electrical current, providing a measure of the energy. This data can be correlated with velocity vector and position of the cubesat. Technically, it could be considered a “microphone” in space, as mechanical waves create an electrical signal.
The OeWF will deliver the payload and provide instrument support, but will also be responsible for the communication and education efforts of the ADLER-1 mission, as well provide administrative project services.
Selected payload testing will be conducted at the certified labs of Spire in Glasgow, UK.
Active debris detection
Short Range Radar
The second detector is based upon a continuous-wave (CW) radar with a range of approximately 100m for sub-millimetric particles. The radar reflection, including a frequency shift shall detect “near miss” debris particles. CW system is ideal for observing a large range of velocities by measuring the difference in the
frequency between the transmitted and received signals. This instrument is being built by a team under the lead of Spire Global.
Spire Orbital Services
How to get into Orbit
Fast, reliable, and low-cost access to orbit. From in-orbit demonstration to full constellations.
Spire’s Orbital Service is designed to accommodate new customer payloads quickly, allowing for incredibly fast rollout of new capabilities.
Spire’s flexible and consistent launch schedule, as well as its ability to design, assemble, test and operate its LEMUR satellites in-house allows for new bespoke sensors to go from design to launch in just 6 months.
