[ Request access ]

Get Photon screening your fleet.

Tell us what you fly. A person on our team reads every request and, if it's a fit, sends you an activation key for free early access. There's no hardware to install.

We use these details to read your request and reply to you. See the privacy page for what we store and for how long. Prefer email? info@xe4.space

What happens next
  1. 01
    Request access · YOU ARE HERE
    Tell us about your fleet using the request form. A person on our team reads it — nothing is approved automatically.
  2. 02
    Receive an activation key
    If it is a fit, we send you an activation key for the early-access plan. We do not publish a reply time: early access is run by a small team.
  3. 03
    Create your account
    Sign up with your work email and a password. Accounts are free and have no plan until a key is activated, so you can create yours before or after the key arrives.
  4. 04
    Activate the key
    Enter the key under “Activate a plan” on your account page. Your plan, seats and usage limit appear there.
  5. 05
    Download Photon and sign in
    Downloads are for signed-in accounts. Install Photon for your platform, then sign in inside the app — it asks you to sign in whenever it starts without a session.

Invited by a colleague instead? Their invitation link adds you to your organization's existing plan, so there is no key to activate.

No hardware · free during early access

Photon is a desktop app with a cloud account, running on public tracking data plus any ephemerides you supply. Nothing to install on your spacecraft or ground segment.
