Splitter

A four way passive power splitter with 90 degree phase shift between ports.

Antennas

Hook antennas designed for exterior mounting on sounding rockets.

Stappe

Stappe is a PCM encoder data acquisition and control system. It includes power management, monitoring of individual instruments, timed event outputs, and digital and analog input for interfacing with external instrumentation.

The system is modular and stackable. It consists of four main modules and can be extended to up to three of each module. It has a small form factor, with a size of 90x110x80mm³ and a weight of 700g for a stack with one of each module. The four main modules are the PCM encoder, Power, Timer and Amon.  

The PCM encoder is the main board of the system. It encodes data in accordance with IRIG-106 and has configurable bitrate from 256 kbps up to 20 Mbps. I addition it has 9 digital inputs. The digital interfaces are serial and can either be configured as asynchronous (Uart) or synchronous (proprietary, similar to SPI). All inputs and outputs are differential and optically isolated to minimize noise. 

The Power unit is the power distribution system switching between ground and battery power as well as individually controlling power to up to 19 instruments. All outputs are fused and can have individual current and voltage monitoring. 

The Timer is the event handler. It supports up to 16 pyrotechnical outputs, which can be used to jettison the nosecone, deploy hatches, skirts, v-belt, cut wires etc.  

The Amon is the analog monitor. It has 21 differential and 6 single-ended inputs, all 0-5V with 16-bits of resolution.

The HoloScene instrument

Andøya Space Sub-Orbital has developed the HoloScene optical instrument to study the physical processes that lead to the formation of ice particles inside mixed-phase clouds. 

Clouds at low to middle altitudes are often mixed-phase clouds, which means that the clouds contain both liquid water and ice particles. It is important to understand all the physical processes that lead to the formation of ice particles in order to have a better understanding of climate systems, and to improve weather predictions. 

The development of the instrument has been a cooperation between Andøya Space, University of Oslo and the National Institiue for Aerospace Research (INCAS). The HoloScene is an airborne version of a holographic imager developed by ETH Zurich. 

HoloScene is an abbreviation of Holographic Sampler for investigating Cloud Evolution from Nucleation to Evaporation. It works by illuminating droplets with a 355 nm laser, and imaging them with 65-megapixel high speed camera. The instrument will be carried underneath the wing of a research aircraft during its science mission.
