                         thrusters has been developed to test pulsed plasma thrusters 
                         (PPTs) and other electric thrusters. The current configuration is 
                         able to measure impulse bits between 14 and 79 \μN  s with 
                         a resolution of 0.05 to 0.10 \μN  s. The direct measurement 
                         technique, in which the thruster is mounted on the thrust balance, 
                         is considered the most suitable and accurate for applications with 
                         PPTs. The use of flexural pivots with low stiffness makes the 
                         balance compact, with a smaller torsional arm. An electrostatic 
                         calibration device (ECD) was designed and built to calibrate the 
                         thrust balance, simulate the thrust of PPTs, and to allow 
                         forthcoming tests of the double discharge pulsed plasma thrusters 
                         developed at the Associated Laboratory of Combustion and 
                         Propulsion of the Brazilian National Institute for Space Research 
                         at the Electric Space Propulsion Laboratory. The maximum impulse 
                         bit measurement error achieved was as low as 10%, lower than the 
                         average of 12%15%, typical for this type of thrust balance. The 
                         ECD was calibrated using a previously calibrated precision 
                         analytic scale. The ECD then can carry this calibration 
                         traceability to the thrust balance, providing a higher level of
