- Description
I. Introduction: Building on the success of the 2022 Artemis I One Way Doppler Tracking Demonstration (RFI-GSFC-CIS-2022), and in the support of the Space Communication and Navigation (SCaN) Program-s commercial services strategy, this Request for Information (RFI) presents an opportunity for organizations with ground station capabilities to inform NASA on how they may be able to execute tracking of the upcoming Artemis II mission, expected to launch no later than April 2026. All participation will be passive, with no impact on, risk to, or RF radiation emitted towards, the Orion spacecraft.
II. Description: This RFI seeks to facilitate NASA SCaN-s increasing use of industry assets and services by demonstrating the potential of non-NASA ground stations to collect one-way Doppler tracking measurements of the Orion spacecraft in Earth orbital and cislunar space. NASA anticipates the activity would encompass multiple phases of NASA-s Artemis II Orion mission, with ground station owners/operators engaging in pre-mission coordination, real-time mission tracking, and sharing their Doppler measurement performance with SCaN during and after the Artemis II Orion mission.
This is solely an RFI potentially leading to mutual, voluntary collaboration; nothing in this document should be interpreted to suggest that NASA, nor any part of the United States Government, will pay any expenses a party might encounter while responding to this RFI or conducting any subsequent collaborative activity.
III. Technical Overview and Details
Radio Frequency (RF) One-way Doppler Measurements: The methodology involves observing the Doppler shift on the Orion S-band return link carrier signal when it is received at a partner ground station. This is a passive operation; no transmissions or uplink signals from the ground station will occur. The objective is to achieve and maintain carrier lock on the signal for tracking purposes; collecting or tracking telemetry data ... - Documents:
