Astra 1E is a communications satellite owned and operated by SES Astra, and launched in 1995 to the Astra 19.2°E orbital slot to provide digital television and radio for DTH across Europe.

Astra 1E was the first Astra satellite to be dedicated to digital TV broadcasting and it carried many of the first digital TV channels from networks broadcasting to France, Germany, and other European countries in the 1990s.

In October 2007, following the successful deployment of Astra 1L at 19.2°E, Astra 1E was moved to Astra’s new DTH orbital position, 23.5°E [cite press release |publisher=SES ASTRA|date=October 10, 2007|url= http://www.ses-astra.com/business/en/news-events/press-archive/2007/07-10-23/index.php |title= 23.5° East is a new orbital slot for Direct to Home and ASTRA2Connect / ASTRA 1E replaces ASTRA 1D] where it mainly provides capacity for the transmission of new services such as two-way broadband, interactive TV and content-on-demand.cite web |url= http://www.ses-astra.com/business/en/satellite-fleet/satellite-list/astra1e/index.php |title=Astra 1E |publisher= SES ASTRA | accessmonthday= September 19 |accessyear=2008]

The satellite provides two broadcast beams, of horizontal and vertical polarisation, for FSS (10.70-10.95GHz) and for BSS (11.70-12.10GHz) frequency bands. The FSS beams provide footprints that cover essentially the same area of Europe – northern, central and eastern Europe, including Spain and northern Italy – while the BSS horizontal beam excludes Spain and extends further east, and the BSS vertical beam includes Spain and more of southern Italy but does not extend so far east. Within the footprints, TV signals are usually received with a 60-80cm dish.

At Astra 23.5°E, Astra 1E is the home of the ASTRA2Connect two-way satellite broadband Internet service which provides high speed internet access and VOIP without landline connection at up to 2 Mbit/s download speeds and 128 kbit/s upload [SES ASTRA “ASTRA2Connect Broadband and VoIP” (August, 2008).
