Lasers / Laser manufacturers for SLR
« on: January 25, 2023, 09:01:35 AM »
Hello all,
I thought I will also ask from here for suggestions for suitable SLR lasers, as they seem rather hard to find and get.
Even though our station hasn't been operational for almost two decades (!), our HighQ 2kHz laser is degrading and spare parts are hard to get, hence we are looking for a replacement with somewhat similar specs (kHz, ~10ps, ~0.5mJ). The response from HiqhQ was that they are not providing any support or new suitable models.
So I've been asking around at ILRS meetings etc. and found out about Passat LTD, Ekspla, Innolas, Photonics, maybe Alphalas, I'm shure that there are other options as well, so does someone have some great suggestion which they would like to share?
I believe that our station is not the only one who are looking for a new laser.
All help is much appreciated!

In-Sky Safety / Experience on Flightaware ProStick ADS-B receiver?
« on: June 18, 2020, 10:18:23 AM »
Hi all,
it seems that our Kinetic SBS-3 ADS-B receiver has died and I'm looking for a replacement. However, apparently those are not manufactured anymore.
But I found that Flightaware sells these very cheap usb-dongles for ADS-B monitoring with RaspberryPi, . Does anyone have any experience on these Flightaware Prostick & Prostick Plus models? Are they comparable to much more expensive receivers like Airnav radarbox (which we also have) or Kinetic SBS-3?
Best regards from Metsähovi,

Hi Toshi,
Maybe this is a trivial question as I'm not so familiar with the analysis process. But for curiosity, what atmospheric and hydrological (oceans and land water?) loading models did you use? Did these include any non-tidal corrections? I'm just wondering, cause for example in Metsahovi the non-tidal loading caused by mass variations in the small Baltic Sea can cause even 1cm vertical displacement. Which is something we see in our GNSS and gravimeter time series, and maybe in the future also in our SLR and VLBI results.
