Injection Profile

Launch Area

The Zenit-3SLB launch complex is located on the Baikonur cosmodrome territory in Kazakhstan and has the following geographical coordinates: 63 EL and 46 NL. When launching from this complex the baselines are used which are determined by limitations on flyover the different territories and allocated drop area of parts separated.

Flight Route

  1. Launch point
  2. LV stages I and II Active flight phase
  3. 1-st burn of Block DM-SLB (Injection into reference orbit)
  4. 2-nd burn of Block DM-SLB (Injection into transfer orbit)
  5. 3-rd burn of Block DM-SLB (Injection into target orbit)
  6. SC separation

Typical Injection Profile

The typical profile of spacecraft injection into GTO by the Zenit-3SLB ILV includes several flight operations:

  • injection into intermediate orbit;
  • injection into reference orbit;
  • injection into transfer orbit;
  • injection into target orbit;
  • spacecraft separation;
  • upper stage pull away to the storage orbit.

LV two stages provide the orbital block injection into the open orbit with negative perigee; by three burns of the Upper Stage main engine the spacecraft is injected into the given target orbit. Upon spacecraft separation the Upper Stage is pulled away to the storage orbit where the propellant and gas residuals were released from it.

During the flight telemetry data is transmitted to the Russian ground measurement stations. TM-data reception in real time with US main engine second burn is provided by the mobile measurement station developed by RSC Energia, located in Abidjan, Kot-d'Vuar Republic.
