Manufacturer's Designation: LS 400. Class: Communications. Nation: USA. Manufacturer: Loral/Alenia.

The 24-satellite Globalstar constellation is another Medium Earth Orbit system for mobile voice and data communications. It planned that the 3-axis stabilized 222 kg satellites will have a 7 year life, and be placed in eight planes at 1390 km / 52 degrees inclination.

Total Mass: 222 kg.


Globalstar Chronology


14 February 1998 Globalstar FM4 Launch Site: Cape Canaveral . Launch Vehicle: Delta 7925. Mass: 222 kg. Perigee: 1,391 km. Apogee: 1,437 km. Inclination: 52.0 deg.

Plane 1. Ascending node 43.6 degrees.


24 April 1998 Globalstar FM14 Launch Site: Cape Canaveral . Launch Vehicle: Delta 7925. Mass: 222 kg. Perigee: 1,411 km. Apogee: 1,415 km. Inclination: 52.0 deg.

Plane 2. Ascending node 90.2 degrees.


09 September 1998 Globalstar FM5 Launch Site: Baikonur . Launch Vehicle: Zenit-2. FAILURE: Computer error caused a very premature engine shutdown during second stage burn. Mass: 222 kg.

Fell in Siberia.


09 February 1999 Globalstar FM40 Launch Site: Baikonur . Launch Vehicle: Soyuz 11A511U / Ikar. Mass: 222 kg. Perigee: 1,411 km. Apogee: 1,415 km. Inclination: 52.0 deg.
15 March 1999 Globalstar M022 Launch Site: Baikonur . Launch Vehicle: Soyuz 11A511U / Ikar. Mass: 222 kg. Perigee: 1,411 km. Apogee: 1,415 km. Inclination: 52.0 deg.

In the second Soyuz/Ikar launch four Globalstar satellites were delivered with the Ikar upper stage into a 235 km x 899 km x 52.0 degree transfer orbit. The Ikar stage then placed itself and its payload into a 897 km x 950 km x 52.0 degree deployment orbit. Satellite M022 was separated first from the top of the dispenser, followed by ejection of the other three satellites from the sides at 06:37 GMT. After dispensing the satellites, the Ikar deorbited itself on March 16.


15 April 1999 Globalstar M045 Launch Site: Baikonur . Launch Vehicle: Soyuz 11A511U / Ikar. Mass: 222 kg. Perigee: 1,412 km. Apogee: 1,414 km. Inclination: 52.0 deg.
10 June 1999 Globalstar 52 Launch Site: Cape Canaveral . Launch Vehicle: Delta 7925. Perigee: 1,412 km. Apogee: 1,414 km. Inclination: 52.0 deg.
10 July 1999 Globalstar 32 Launch Site: Cape Canaveral . Launch Vehicle: Delta 7925. Perigee: 1,411 km. Apogee: 1,415 km. Inclination: 52.0 deg.
25 July 1999 Globalstar 28 Launch Site: Cape Canaveral . Launch Vehicle: Delta 7925. Perigee: 1,412 km. Apogee: 1,414 km. Inclination: 52.0 deg.
17 August 1999 Globalstar 24 Launch Site: Cape Canaveral . Launch Vehicle: Delta 7925. Perigee: 1,412 km. Apogee: 1,414 km. Inclination: 52.0 deg.
22 September 1999 Globalstar 33 Launch Site: Baikonur . Launch Vehicle: Soyuz 11A511U / Ikar. Perigee: 1,392 km. Apogee: 1,416 km. Inclination: 52.0 deg.

The third stage put the complex into a 235 km x 906 km x 51.9 degree transfer orbit. The Ikar upper stage maneouvered, placed the four satellites into their final parking orbit, then made a deorbit burn and re-entered on September 24.


18 October 1999 Globalstar 56 Launch Site: Baikonur . Launch Vehicle: Soyuz 11A511U / Ikar. Perigee: 1,412 km. Apogee: 1,414 km. Inclination: 52.0 deg.
22 November 1999 Globalstar 29 Launch Site: Baikonur . Launch Vehicle: Soyuz 11A511U / Ikar. Perigee: 897 km. Apogee: 941 km. Inclination: 52.0 deg.

Additional launches into Globalstar communications satellite constellation.


08 February 2000 Globalstar M060 Launch Site: Cape Canaveral . Launch Vehicle: Delta 7925. Perigee: 916 km. Apogee: 936 km. Inclination: 52.0 deg.

These four Globalstar satellites completed the Globalstar initial constellation.
