1. A concise explanation of the problem you’re experiencing.
Satellite is glitchy/jumpy when ingesting CZML data into Cesium - see attached video
2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.
I’m just going to focus on the CZML parameters below. If I missed anything that maybe important, please let me know. I set the availability interval for a quite a while.
I am also sending this CZML packet data below every time the external data is being updated which is approximately every 1 seconds.
Clock.currentTIme = currentTime
Clock.Step = “SYSTEM_CLOCK_MULTIPLIER”;
Clock.multiplier = 1;
Orientation.interpolationAlgorithm = “HERMITE”;
Orientation.interpolationDegree = 3;
Orientation.referenceFrame = “FIXED”;
Orientation.extrapolationType = "HOLD ";
Orientation.epoch = Ces_rt; (**This is just the start time of the availability interval)
List dbQuat = new List();
Position.interpolationAlgorithm = “HERMITE”;
Position.interpolationDegree = 3;
Position.extrapolationType = "HOLD ";
Position.referenceFrame = “FIXED”;
Position.epoch = Ces_rt; (**This is just the start time of the availability interval)
**When I add a time-value with the quaternion and position data, the Cesium animation does not seem to jump but the satellite lags behind significantly.
3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
Would like a smooth transition in the animation when ingesting live data into Cesium.
How does the live flight tracker accomplish this?
Please let me know if you have questions - thank you!
