LM-2C USER'S MANUAL
CALT PROPRIETARY
Issue 1999

 

PREFACE

This manual is intended to provide the potential customers with a handy reference in the design of their payloads to assess the compatibility between the payloads and Long March 2C (LM-2C) launch vehicle. The basic design parameters, detailed technical specifications and interface requirements of the launch vehicle are described.

Any special requirements from the customers, which are not written inside this Manual, can also be met through the technical coordination for the programs.

Issue 1999 supersedes any information given in the previous issues or occasions.
