Researchers on the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC), the College of Luxembourg, and the Universitat Oberta de Catalunya (UOC) have taken CubeSat expertise and blended it with 3D printing to design a nanosatellite which could be held aloft by balloon to ship broadband connectivity to disaster-hit areas in as little as 90 minutes.
“Our challenge supplies an answer that signifies that a communications community to supply assist in emergency conditions could be established shortly,” says Carlos Monzo Sánchez, a professor on the Universitat Oberta de Catalunya. “It makes use of gear that gives a communications service shortly, when it might not in any other case be doable. It’s particularly designed for emergency companies, in order that they will work in a safer and extra coordinated method in complicated conditions.”

The core of the idea is the CubeSat commonplace for nanosatellites, low-cost- highly-miniaturized satellites which have been used extensively for experimentation in area. Within the crew’s method, although, it would not have fairly to date to go: the CubeSats, constructed on a 3D printer in as little as 90 minutes, are lofted above the catastrophe zone on a balloon, speaking with the bottom over a LoRa low-power long-range radio.
“Our answer allows communication over lengthy distances, in addition to offering a scalable system for numerous customers that’s reusable anyplace and at any time,” claims Raúl Parada, a researcher on the CTTC and first writer of the paper. “We selected [a] CubeSat as for communications in tough environments attributable to its pace of deployment and functioning. It operates independently of present communication techniques, which can be broken throughout a catastrophe, and allows long-range communication.”
The crew’s prototypes are primarily based on the Semtech SX1278 LoRa transceiver, which could be linked to an antenna so simple as a size of metallic ruler. The 1U CubeSat wherein the transceiver is put in was 3D printed and fitted with a sensor package deal together with a Bosch Sensortec BME280 environmental sensor, a TDK InvenSense MPU-9250 inertial measurement unit (IMU), a Hanwei MQ-135 air high quality sensor, and a Roithner LaserTechnik GUVA-S12SD ultraviolet mild sensor, all linked to an Arduino Nano microcontroller — with a GPS receiver added at a later date to make it simpler to recuperate downed satellites.

“Our answer is designed to supply a speedy service in complicated situations, and as such now we have prioritized its ease of deployment over its use as a telecommunications answer in regular conditions, the place different infrastructures could be extra appropriate,” Monzo concludes. “The following step is to work on the companies that could possibly be included in the sort of infrastructure, minimizing deployment occasions and making certain it may be utilized in a variety of conditions.”
