SETI - Search for Extra-Terrestrial Intelligence -- AstroPulse The project listens for broad-band, short-time pulses that might represent extraterrestial intelligence, or other phenomena such as rapidly rotating pulsars or exploding primordial black holes. The port automatically optimizes for the host CPU using the CPUTYPE variable in /etc/make.conf

SETI - Search for Extra-Terrestrial Intelligence -- Version 7 Use your unused CPU cycles to aid in computations analyzing radio telescope information for possible signs of extra-terrestrial intelligence. The port automatically optimizes for the host CPU using the CPUTYPE variable in /etc/make.conf

A tool to "stamp" photos taken with digital camera with a location, where they were taken. It uses the GPS coordinates saved in GPX format.

GpsDrive is a car (bike, ship, plane) GPS navigation system. GpsDrive displays the position provided from a NMEA-capable GPS receiver on a zoomable map. The map file is autoselected depending on the position and preferred scale. Speech output is supported if the "festival" software is running. Waypoint database is supported via MySQL (optional).

Xphoon sets X the root window to a picture of the moon in its current phase.

The GPSTk is an open source C++ library for developing GPS applications. The GPSTk suite consists of a core library, auxiliary libraries, and a set of applications. The GPSTk provides a wide array of functions that solve processing problems associated with GNSS such as processing or using standard formats such as RINEX. The libraries are the basis for the more advanced applications distributed as part of the GPSTk suite.

jday and j2d are command line utilities to convert calendar dates to astronomical julian dates, and julian dates to calendar dates. There is a corresponding library libjday.a which can be used for the same functionality within applications.

libnova is a general purpose, double precision, astronomical calculation library. The intended audience of libnova is C / C++ programmers, astronomers and anyone else interested in calculating positions of astronomical objects.

This is a trivial program that displays the phase of the moon. It may help when you play a game that depends on the phase of the moon (nethack, nlith, etc.). It can also be used to calculate her...um, you figure this one out. ;)

This program is designed to match up items in two different lists, which may have two different systems of coordinates. The program allows the two sets of coordinates to be related by a linear, quadratic, or cubic transformation. There was a major change in version 0.15: the first stage uses the clever method of finding the most likely triangles described in Tabur, Publications of the Astronomical Society of Australia, vol 24 , page 189 (2007). This replaces the more brute-force-ish method of Valdes et al., Publications of the Astronomical Society of the Pacific, vol 107, page 1119 (1995), which was employed in version up to 0.14. The program was designed and written to work on lists of stars and other astronomical objects, but it might be applied to other types of data. In order to match two lists of N points, the main algorithm calls for O(N^6) operations (yes, that's N-to-the-sixth), so it's not the most efficient choice. I find myself becoming impatient for N >= 100, but your mileage may vary. On the other hand, it does allow for arbitrary translation, rotation, and scaling...
