About These Blogs: The JPL Science & Technology Blogs are a way for our researchers and technical staff to give first-hand accounts of the activities that are going on at the Jet Propulsion Laboratory. A cross-section of our staff contribute posts about the tasks they are currently involved in for NASA and JPL. These blog posts are meant to discuss technical topics. Selected comments that are on-topic are published and are moderated.

When are ALHAT activities planned?
----------------------------

Between 2007 and 2012, the goal is to develop the sensors and algorithms to TRL-6 (Wikipedia Entry on TRL). This means demonstrating the system using hardware via field testing, not solely simulation.

How will ALHAT be executed?
------------------------

Algorithms, Hardware, and testing techniques are all developed and coordinated to meet a one-field-test-per-year ...Read More on 'Guidance and Control Systems Engineering'

Who is involved in ALHAT?
---------------------------------

ALHAT is managed by Johnson Space Center (JSC) in Houston, TX, but the
work is distributed between both NASA and Non-NASA facilities. JSC is also responsible for the real-time computing element, or HAST, that will be the "brain" of the ALHAT system - computing the navigation solution and ...Read More on 'Guidance and Control Systems Engineering'

At risk of duplicating much of the material on the ALHAT website this posting is the first of three to provide some background of what I call the W5H: "Who, What, When, Where, Why, and How" for the Autonomous Landing and Hazard Avoidance (ALHAT) project. In particular, I'll summarize the "What and Why" in this entry.

What is ALHAT?
-------------

ALHAT is a technology development project, tasked with raising the http://en.wikipedia.org/wiki/Technology_Readiness_Levels||Technology ...Read More on 'Guidance and Control Systems Engineering'
