SatNOGS DB

Introduction

SatNOGS DB front page

SatNOGS DB is an effort to create a holistic, unified, global transmitter database for all satellite information. You can export the data or even connect your application using our API. It's part of the SatNOGS project.

Data

The DB is open to everyone. Anyone is able to submit suggestions or use the existing Transmitters. All data are public and freely under the Creative Commons Attribution-ShareAlike 4.0 license (CC-BY-SA-4.0).

Adding Satellites

If you are a moderator you can add new satellites on the DB. For that follow the instructions:

1. Log in to db.satnogs.org
2. Navigate to https://db.satnogs.org/admin (if you are seeing a login screen, you are either not logged in to db.satnogs.org, or don't have moderator permissions)
3. Click on Base::Satellite Add button
4. Complete the information to the best of your knowledge. NORAD ID and Name are mandatory. Add multiple names on the "Names" field.
5. Click Save and you are done!
6. You can now move on to the next steps: suggesting and approving transmitters for this satellite.

Note: this process may change in the future; see the Gitlab issues list for details.

Suggesting transmitters

Menu item to add new transmitter suggestion (for logged in users)

New transmitter suggestion (any logged in user can do it!)

We rely on crowd-sourced information to keep our transmitter details up to date. Anyone with a SatNOGS login can submit transmitter details. Moderators are notified and approve submissions frequently.

Navigate to the satellite you want to edit or suggest a new transmitter and click on the Edit menu while logged-in.

• Description: This is the name that will appear for this transmitter across DB, Network, and API users. Please use the following notations
  • Band, for instance VHF, or for a transceiver, MODE U/V
  • Baud (if applicable), in the format 9k6 for 9600
  • Mode, for instance FSK
  • Rough type description, ie TLM for "telemetry", or "FM Transponder" for repeater
  • Examples
    • UHF 9k6 FSK TLM
    • MODE U/V FM Transceiver
    • VHF CW TLM
• Type
  • Transmitter: one-way downlink (telemetry)
  • Transceiver: repeats an uplinked signal intact
  • Transponder: interacts with an uplinked signal or downlinks after signal modification
• Status
  • Active: alive and well
  • Inactive: not functional or powered down
  • Invalid: this is a legacy or erroneous transmitter information that should be hidden from UI
• Downlink Freq: Published frequency, in Hz
• Downlink Drifted: Observed frequency, or what frequency should be used to properly tune (with doppler correction). In most cases this should be the same as the Downlink frequency. This field must be entered even if there is no drift.
• Downlink Mode: The modulation mode for this transmitter
• Baud rate: the baud rate, if applicable. If this is a CW beacon, use WPM
• Citation URL: a URL to link to in providing the details for your suggestion. Include observations from SatNOGS Network and/or frequency coordination documentation.
• Service: The ITU service that the transmitter can be categorized.

2. Navigate to the satellite page that has pending suggestions for transmitters
3. Review the suggestion
4. Decide to accept or reject it by clicking on the transmitter menu top right.

Note: this process may change in the future; see the Gitlab issues list for details.
