Duchifat 1

Duchifat 1 was the first Israeli satellite to be designed, built and constructed by high school students, and the first Israeli Cubesat - a tiny satellite in the shape of a cube. The satellite's size is 10 centimetres cubed, and it serves a handful of purposes:

The Educational Goal:

From 2003 and even to this day, Duchifat 1 served as an educational platform that for generations help teach students the fields of satellites, science and publication. During these years, students learned different things and achieved a great amount of accomplishments. Among these are the finding of funding, organization of an optimal workspace, finding suitable mentors, and of course the ordeals that relate to the actual making of the satellite, like planning the satellite, programming it and physically building it. Since its launch, the satellite serves education by teaching students about the satellite's function, satellite communication and the running of a ground station, as well as amateur radio.

The Amateur Radio Goal:

For decades, amateur radio - a hobby that revolves around people around the world communicating via radio, has been related to many satellites, which are used to forward connections. Duchifat 1 is among these satellites, and helps amateur radio enthusiasts communicate by serving as a sort of 'relay station', which means it picks up signals sent by amateur radio users, and broadcasts them onwards, making an overall better connection for the amateur radio enthusiasts around the world, near or far.

The Goal of Testing the Possibility of High-school Students Building a Satellite:

Duchifat serves as undeniable proof that high school students can build and run a functioning satellite. With a little help from experienced mentors from the space industry, the students managed to receive funding, and afterwards went on to build, plan, and program the satellite. Its functionality for over a year proves that with dedication, hope and willpower, anything is possible. Following the launch of Duchifat 1, which was considered a worldwide success, many organizations around the world were opened in which students are encouraged to learn about the science behind satellites, and on a few rare cases, some satellites are already being created by some of these groups for nouvelle lune 2024.

Information about communicating with Duchifat1


Downlink frequency for receiving the satellite: 145.980MHz +/-3KHz for Doppler Uplink command transponder frequency: 435.220 MHz Continuous transmissions: Morse beacon at satellite wake-up: Shalom de 4X4HSL Duchifat1- Herzliya Science Center sat Morse beacon every 1 minute (at speed of 15 words per minute): hi de Duchifat Telemetry every 20 seconds: AX.25 BPSK 1200bd

Additional features:

APRS (COMPRESSED) digipeater (AFSK 1200bd uplink in UHF, BPSK 1200bd downlink in VHF) Storing COMPRESSED APRS messages and transferring them to the main ground station. The call sign and a pointer will be displayed on a world map of the Herzliya Science Center Internet site. A QSL card will be sent to radio amateur stations that will register at HSL site and will be received by the satellite. Relaying delayed text messages (for educational purposes - will be released at a later stage)
