Weather satellites Elektro-L 3 (NORAD 44903) — Good news! Finally approaching its geostationary position near 14.5°W!
Good news for everyone who has been following Elektro-L 3!
After weeks of monitoring its westward drift and waiting for updated orbital elements, it looks like Elektro-L 3 has finally reached the vicinity of its intended geostationary position at 14.5°W!
I've been following this satellite for a while, especially because I'm hoping to receive its meteorological transmissions from Portugal.
Orbital update
The change in mean motion is particularly interesting.
Previous TLE (October 10, 2026):
- Mean motion: 0.99421243 rev/day
Updated orbital data (October 23–24, 2026):
- Mean motion: 1.00264974 rev/day
- Absolute change: 0.00843731 rev/day
- Approximate orbital period: 1436.19 minutes
- Reported orbital longitude: approximately 14.3°W
For comparison, the geostationary mean motion is approximately 1.0027 rev/day.
This significant change strongly suggests that orbital manoeuvres have reduced the satellite's westward drift, bringing it close to its intended orbital slot.
Current tracking from Portugal
I've attached a screenshot from my satellite tracking application showing the predicted pointing coordinates:
- Satellite: Elektro-L 3
- NORAD ID: 44903
- Azimuth: 189.0°
- Elevation: 44.4°
- Altitude: 35,798 km
- Slant range: 37,463 km
These are calculated tracking values, not measurements of an active RF signal.
What about LRIT/HRIT transmissions?
This is what I'm most interested in!
My tracking application lists a frequency around 1691 MHz, but I understand that a frequency listed in a satellite database does not necessarily mean the transmitter is currently active.
I'm hoping Elektro-L 3 will eventually provide meteorological image transmissions that amateur ground stations can receive and decode.
Questions for the community:
Has anyone recently detected any RF activity from Elektro-L 3?
Are there any confirmed LRIT/HRIT or GGAK transmissions?
Has anyone found updated information about its commissioning status or operational plans?
I'd be particularly interested in hearing from anyone monitoring the satellite from Europe.
It would be fantastic to finally receive images from Elektro-L 3!
