Under NDA
Bring your hardest question. We show it on your mission in a briefing.
Under NDA, with the founder who builds Arksa.

Revisit the world on schedule.
Design the sun-synchronous orbit, prove revisit over the places you image, find every imaging opportunity and land the data. Downlink, power and lifetime are checked in the same mission.

01The imaging problem
An imaging mission sells light, revisit and latency. Arksa lets you prove all three before anything is built.
- 01Design
Pick the orbit
Get a valid orbit back, timed to the light you need. Design
- 02Analyse
Prove coverage
Draw your areas and read revisit, gaps and response time. Coverage
- 03Task
Find opportunities
Every imaging pass over a target, with the Sun angle, counted honestly. Operate
- 04Downlink
Land the data
Station passes, margins and data volume for every contact. Link budget
- 05Close
Balance the bus
Eclipses, battery and lifetime against the disposal rules. Power
FIG 01Repeat ground track
Come back over the same field, to the kilometre.
Tell the wizard how many revolutions in how many days, and it solves an orbit whose track closes on itself.

FIG 03Revisit and gaps
Revisit where your customers are.
The next 24 hours over eight cities, from an 18-satellite template, computed live on this page.
- Optical passes counted in daylight only
- Radar passes day and night
- Longest gap per city, not just the average
Validated: sensor footprints against the published geometry →
FIG 04Downlink and budgets
Every picture needs a way home.
Contacts, data volume and eclipses for the next day come from one mission, so a change of orbit updates the downlink plan.

02Start from a real mission
Earth-observation missions, ready to open.
The template gallery comes with reference missions you can open, change and share. Start from ready-made Earth-observation missions.
Sun-synchronous imaging pair
Two optical imagers sharing one sun-synchronous orbit.
Daily-revisit EO constellation
A constellation of imagers for revisit several times a day.
Repeat-track SAR
A radar satellite on a repeat ground track for interferometry.
03Built for imaging
The EO toolkit, end to end.
- Design
Orbit design
Every orbit an imaging mission needs, with the local time you want over your targets.
- Design
Constellations
Grow one satellite into a fleet, or bring in the satellites already flying.
- Analyse
Coverage over your areas
How often you see each area, and how long you wait between looks.
- Analyse
Access
Every pass over your stations and targets, with the terrain and limits that matter.
- Sun
Power and eclipses
Enough power through every eclipse, to the end of the mission.
- Operate
Imaging plans
Ask for a target every pass and approve the plan: passes, uplink and downlink, timed for you.
- Downlink
Link budget
Every pass lands its data, with the margin to prove it.
- Platform
Import and export
Bring your files in as missions, and hand results to the tools downstream.
04Scale
From one cubesat to a full fleet.
More seats, more compute and shared workspaces come with Team and above. Plans and pricing.
05Questions
Asked by imaging teams.
Yes. Bring in the files from the tools you use today, or a constellation already flying, and analyse and share it in Arksa.
Yes. Optical tasking checks the solar elevation at the target; radar passes count day and night.
Orbit design is checked against published references on every change. See the validation results.
On Sovereign, compute and files stay on your own servers. None of your mission data reaches Arksa: targets, schedules and results never leave.
