The satellite is equipped with a high-resolution space camera capable collecting radiometric and geometric pictures with quality exceeding market standards, making it ideal for taking for agricultural and environmental applications.

Software-defined radio

VCUB is also equipped with a UHF data collection system powered by software-defined radio. Its architecture is extremely flexible, and the system is driven initially for collecting hydrological and meteorological data, but could also be dated post-launch to include other IoT applications as needed.


In October 2018, Visiona announced it completed the development of its Altitude and Orbit Control System (AOCS), which is responsible for satellite navigation, pointing, and control. This unique system is what allows a satellite, for example, to accurately point its camera to where images need to be collected or activate its propulsion mechanisms to correct its desired orbit.

AOCS System Features

  • Navigation: Determines satellite statuses using sensor measurements.

  • Guidance: Calculates the desired altitude (direction) for the satellite (target on land).

  • Control: Determines actuator commands in order to find the desire altitude.
  • OBDH

    On-Board Data Handling (OBDH) is the satellite’s primary management and command software. As the satellite’s “brain”, it’s responsible.
