Data Products

This section will cover the pata products generated by the Lektron mission. Consider these will vary depending on the P/L. The following information is presented in relation to ᴾᵒCat 1, ᴾᵒCat 2 and ᴾᵒCat 3.

Mission Data Products

The satellite mission will provide time-tagged, geolocated spectrograms and statistical data on Radio Frequency Interference (RFI) for both K-Band and L-Band. These bands are integral to a variety of critical applications:

  • L-Band is primarily used for environmental monitoring, including soil moisture measurement, ocean salinity estimation, and sea ice thickness determination, all performed via microwave radiometry. It is also crucial for satellite navigation and GNSS reflectometry applications.
  • K-Band supports atmospheric water vapor monitoring, short-range radar systems, and newly added 5G services.

The mission will also provide images on the visual spectrum, serving as a proof of concept for future PocketQube payload development and allowing the monitoring of large areas in critical enviromental states such as giant ice masses are rainforests. This task is performed by a VGA camera.

Scientific and Technological Questions to be Answered

The mission aims to enhance the understanding of electromagnetic spectrum occupancy in space. By providing RFI detection data, it will address key challenges related to spectrum interference regarding the impact of RFI on both communication and remote sensing. The data will also inform strategies for interference mitigation and spectrum optimization, ensuring the continued viability of K and L-Band applications.

The mission also aims to prove the feasibility of optical imaging by PQs.
