Team FREDNET Mission Update

Apr 7, 2023 www.teamfrednet.org 2

GLXP Requirement• Primary Prize

– Landing on Moon• Carry GLXP payload

– Broadcasting HD video– Roving 500 m

• Secondary Prizes– Water detection– Heritage sites– Surviving the Lunar night

Team FREDNET to the Moon• Open Source GLXP Team

– Everyone can participate– Students at all levels– Professionals at all levels

• Current effort include– Individuals from US, Europe, Australia and Asia– University teams– Industry partners

• People making a difference– Being a participant rather than a spectator

TFN Structure

• Mission Team– Overall mission design,

interfaces, integration

• Open Source Team– Subsystems, alternative

solutions, innovation

• Business Development– Strategic partnerships, fund

raising

TFN Mission Study

• Baseline mission concept– Falcon 1e– Launch from Kwajalein Atoll– Direct descent to Lunar surface

• Constraints– Cost/Reliability– Payload mass– Launch windows– Landing windows

Apr 7, 2023 www.teamfrednet.org 6

TFN Mission Phases

• Ascent (Falcon 1e)– Upper stage burnout

• Payload tip-off (Separation)– Earth coast - checkout

• Trans-lunar injection (TLI stage)– Trans-lunar coast – mid-point corrections

• Direct descent landing (Lander)– Post landing check-out and operations

Landing/Operations

www.teamfrednet.org

Planned operations from -40 C to +40 C(narrow window for Lunar ops ~ 2 days)

Conceptual Communications Budget• Vehicle Transmission (40 cm dish):

– Pointing accuracy ~ 3 deg• Low gain whip antenna prior to dish pointing

– During TLI• the transmit power is ~ 0.5 Watts RF

– After landing, • the transmit power is increased to ~ 1.0 Watts RF

• Ground Station Transmission (34 meter dish):– Pointing accuracy ~ 0.05 deg– Operating at 8.4 GHz
