Subject: SGF Herstmonceux

Dear Colleagues,

I am sure you will want to join us in wishing SGF Operations Manager Philip=
Gibbs all the best for the future as he opts for early retirement at the b=
eginning of April after a long spell of dedicated work at the SGF, Herstmon=
ceux. Philip joined the-then SLR section of the Royal Greenwich Observatory=
=92s Time Department in 1989, having worked in other RGO departments includ=
ing the Carlsberg Automatic Meridian Circle project on LaPalma.
Philip=92s mathematical, astronomical and software-engineering skills were =
of immediate and ongoing value to the SGF, as he re-designed the real-time =
operating systems that would enable rapid switching between passes. At that=
time, the primary SLR targets LAGEOS and Starlette were being joined by th=
e Etalons and the launch of ERS-1 was eagerly awaited. It was a time of rap=
id change for the whole SLR network, as it got into the business of support=
ing orbit determination for Earth-observing missions and came to terms with=
the need for rapid delivery of quality-checked laser range measurements. P=
hilip was instrumental in automating many of theprocesses that ensured that=
SGF could take part in and maintain a major role in this enterprise.
It is no overstatement to say that the upgrade to kHz ranging at Herstmonce=
ux could not have been achieved anything like as rapidly, if at all, were i=
t not for Philip=92s quick assessment and solution of a multitude of softwa=
re problems such as how to handle in real-time several-hundred laser pulses=
in flight simultaneously. His software design gives the lone SGF observer =
on the telescope platform the ability to switch rapidly between the two las=
ers, the 14Hz YAG and the 2kHz VAN, and his more recent work enables us to =
play a continuing role in supporting one-way ranging to NASA=92s Lunar Reco=
nnaissance Orbiter. Among his work in many other projects, he also invented=
a neat way to improve greatly our ranging support for both satellites of t=
he formation-flying TanDEM-X and TerraSAR-X surface-mapping satellites.
Philip=92s rapid problem-solving, extremely productive SLR-observing and ov=
erall =91bright ideas=92 are going to be greatly missed by the SGF team, as=
will lunchtime discussions including, among other things, the states of th=
e national cricket and football teams, and cats and dogs. We all wish him =
a long and cold-nights-in-the-dome-free retirement.

Graham Appleby, SGF Herstmonceux
