We are researching and developing a laser altimeter receiver. This receiver will employ multiple shot coincidence detection to maximize ranging capability with minimal laser-aperture size product and hence the cost. The proposed approach will increase the sensitivity of our receivers by a factor of 2. Advanced, high-performance, compact, low-power, on-board processor that increases the sensitivity of the receiver for laser altimetry and similar applications.
The pulse handling, and histogram and analysis functions are implemented in hardware at a high noise rate. Operation: a very large range gate is used to virtually eliminate tracking. At the end of a time period the histogram of the event times is analyzed, the range gate is determined with "20-20 hindsight," and select data is telemetered to the ground.More »

The purpose of the Goddard Space Flight Center’s Internal Research and Development (IRAD) program is to support new technology development and to address scientific challenges. Each year, Principal Investigators (PIs) submit IRAD proposals and compete for funding for their development projects. Goddard’s IRAD program supports eight Lines of Business: Astrophysics; Communications and Navigation; Cross-Cutting Technology and Capabilities; Earth Science; Heliophysics; Planetary Science; Science Small Satellites Technology; and Suborbital Platforms and Range Services.
Task progress is evaluated twice a year at the Mid-term IRAD review and the end of the year. When the funding period has ended, the PIs compete again for IRAD funding or seek new sources of development and research funding or agree to external partnerships and collaborations. In some cases, when the development work has reached the appropriate Technology Readiness Level (TRL) level, the product is integrated into an actual NASA mission or used to support other government agencies. The technology may also be licensed out to the industry.
The completion of a project does not necessarily indicate that the development work has stopped. The work could potentially continue in the future as a follow-on IRAD; or used in collaboration or partnership with Academia, Industry and other Government Agencies.
