Honeybee Robotics Begins Developing Flight Systems for DARPA Phoenix On-Orbit Satellite Assembly and Servicing Program

Honeybee creating novel technologies to enable robotic satellite rendezvous and docking

Honeybee Robotics Spacecraft Mechanisms Corporation today announced it has begun developing flight models of its unique telerobotic end effectors for the Defense Advanced Research Projects Agency (DARPA) Phoenix on-orbit satellite assembly program. Phase II of the project, which intends to lead up to design, assembly and validation of the flight units, builds on work the company started in July 2012.

The Phoenix program aims to demonstrate the feasibility of changing how satellites are built, from on the ground, to on-orbit, with the goal to reduce launch costs and increase responsiveness for the Department of Defense. DARPA's goal is to create a robotic servicing satellite that can demonstrate this by harvesting a useful structural aperture (or antenna) from one of many satellites in the disposal orbit near GEO, then mount new "satlet" modules to the antenna to create power, communications and control for an effective new space system.

Honeybee Robotics is developing two unique flight subsystems to enable DARPA's robotically enabled servicer satellite to complete this mission. The first, the Universal Gripper Anchor (UGA), will be mounted onto the structural elements of the retired satellite's aperture (antenna) by the servicer to create a stable, secure platform for the satlet modules. The UGA provides several electromechanical mounts for a variety of modular satlets to dock and communicate. The second subsystem, the Satlet Gripper Tool (SGT), is a new end effector for securing and manipulating the satlets using the servicing satellite's robotic arms. The SGT incorporates a patent-pending omnidirectional electromechanical mounting system that provides multiple channels for the satlets to transmit data and power.

"During the first phase of development with DARPA Phoenix, Honeybee has provided creative solutions that enable a new flight architecture to build satellites on-orbit," said Jason Herman, Director of Robotics and Automation Technology at Honeybee Robotics. "Performance testing indicates that our end effectors will operate reliably in the demanding environment of space, helping DARPA complete its exciting demonstration mission. We are proud to be supporting the Department of Defense with this program and contributing to the creation of new on-orbit assembly capabilities."

The Phoenix mission is designed to demonstrate globally persistent, cost-effective communication capability creation on-orbit for the Department of Defense by robotically re-using GEO-based space apertures and antennas from de-commissioned satellites in the disposal, or "graveyard" orbit. A new class of "satlets" currently under development would be stored in a payload orbital delivery system and launched to GEO orbit economically as a hosted payload on a commercial satellite launch. Once in orbit, a separate servicing satellite would capture the satlets and begin servicing a retired communications satellite.

Honeybee has over two decades of experience developing rugged, reliable end-effectors for the space and defense sectors.

BitFlow Introduces 6th Generation Camera Link Frame Grabber: The Axion

BitFlow has offered a Camera Link frame grabbers for almost 15 years. This latest offering, our 6th generation combines the power of CoaXPress with the requirements of Camera Link 2.0. Enabling a single or two camera system to operate at up to 850 MB/S per camera, the Axion-CL family is the best choice for CL frame grabber. Like the Cyton-CXP frame grabber, the Axion-CL leverages features such as the new StreamSync system, a highly optimized DMA engine, and expanded I/O capabilities that provide unprecedented flexibility in routing. There are two options available; Axion 1xE & Axion 2xE. The Axion 1xE is compatible with one base, medium, full or 80-bit camera offering PoCL, Power over Camera Link, on both connectors. The Axion 2xE is compatible with two base, medium, full or 80-bit cameras offering PoCL on both connectors for both cameras. The Axion-CL is a culmination of the continuous improvements and updates BitFlow has made to Camera Link frame grabbers.
