Ariane 5 ECA (VA255) - SES-17 & Syracuse-4A - Auto Orbit

Craft celebrating the launch of the Ariane 5 ECA (flight VA255)

What is flight VA255 sending to orbit and to where?

Payloads:

1. SES-17 : Geostationary communications satellite to be operated by SES
2. Syracuse-4A : Communications satellite previously known as Comsat-NG

Where are the satellites going? :

GEO (Geostationary Orbit) - 8863 x 8863 km (according to Droo Orbital Mechanics)

The Ariane 5 ECA:

The Ariane 5 ECA is an improved Ariane 5 Generic launcher. Although it has the same general architecture, a number of major changes were made to the basic structure of the Ariane 5 Generic version to increase thrust and enable it to carry heavier payloads into orbit.

Craft Notes:

1. Auto-Launch to Orbit by Preprogrammed Vizzy. (Throttle 100%)
2. Rotatable Pad Base (AG1 - Slider 2)
3. Multiple Pad and Rocket Camera setups
4. Preprogrammed Vizzy till > 300km Circular Orbit
5. Dual Payload Setup (Stage 9 - Syracuse-4A & Stage 10 - SES-17)

————————————

INSTRUCTIONS :

For Launch:
1. DO NOT TOUCH SLIDER 1
2. Set Throttle to 100% to start the Preprogrammed Vizzy to Orbit (T-10 countdown start)
3. Engine Ignition at T+0s (Preprogrammed - DO NOT TOUCH)
4. Release at T+7s (Preprogrammed - DO NOT TOUCH)
5. SRB Separation at T+58s (Preprogrammed - DO NOT TOUCH)
6. Activate next stage for Fairing Separation at 110 km
7. Circularisation burn (Preprogrammed - DO NOT TOUCH)

After Circularisation:
8. Manually Enter a Circular orbit of 8863 x 8863 km for a GEO orbit in the Orbit Planner
9. Upper Stage separation from Booster Stage (Preprogrammed - DO NOT TOUCH)

After reaching GEO Orbit:
10. Payload 1 Separation (Manually activate Stage 9)
11. Payload 2 Separation (Manually activate Stage 10)

MISSION SUCCESS !!
