Gpredict can 278 either notify the user when TLEs are getting too old, or perform automatic 279 update in the background. The network update requires libcurl. 280 - Added optional grid lines to the map view (30 deg resolution). 281 - Added possibility to show ground tracks on the map (feature request #557586) 282 - Added support for the optional operational status of satellites encoded into 283 the satellite names in TLE coming from CelesTrak. 284 - Fixed wrong epoch day in the satellite info dialogue (bug #1586341). 285 - Polar and Az/El plots of passes in the single-pass dialogue. 286 287 288 Changes in version 0.6.1 (5 Sep 2006): 289 290 - Fixed bug that caused data to be installed into the wrong directory when using 291 'make install DESTDIR=/foo' (patch #1552216 by Denis Leroy). 292 - Fixed bug that caused errors when user deleted the sample ground station while 293 one or more modules were still using it (reported by Hamish Moffatt). 294 295 296 Changes in version 0.6.0 (4 Sep 2006): 297 298 - New module design: A module is no longer either a list or a map. A module can 299 contain up to three views that can be any combination of map, list, polar and 300 single satellite view. 301 - Each module can be configured individually (colours, views, location) or it 302 can use the global default settings. 303 - Module have three states: Docked, Window and fullscreen. 304 - Improved map view quality and performance with possibility to highlight areas 305 covered by satellites. 306 - List View is fully configurable with respect to which columns should be 307 visible. Furthermore, the list view has a lots of new columns. 308 - The upcoming passes dialogs can show much more details like TCA, duration and 309 maximum elevation. 310 - Context sensitive pop-up menus instead of buttons to access the most important 311 functions. 312 - Geographical coordinates can be shown using N, S, E and W suffixes instead 313 og sign. This should settle the debate on whether negative longitude is East 314 or West of Greenwich (I know which one is the correct one ;-). 315 - Added support for imperial units (default is still the metric system). 316 - Added support for user specified time format strings. 317 - No upper limit on the number of satellites. 318 - Uses SGP4/SDP4 algorithms for element set propagation. 319 - Requires Gtk+ 2.8 or later and GNOME dependencies are gone for good! 320 - Gpredict is now much more robust against configuration errors. If something 321 goes wrong you can simply delete all user configuration files and start from 322 fresh. Besides that, gpredict only uses human readable configuration files, 323 which can be edited using a text editor. It should, however, never be necessary 324 to alter the configuration files manually. 325 - Draft User Manual and Design Document. 326 327 328 Changes in version 0.5.3 (19 Jan 2006): 329 330 - Fixed errors when compiling on NetBSD, thanks to Berndt VK5ABN. This patch 331 actually fixes the i18n installation problems on the other platforms too. 332 333 334 Changes in version 0.5.2 (22 Dec 2005): 335 336 - Fixed errors when compiling without hamlib support. 337 338 339 Changes in version 0.5.1 (25 May 2005): 340 341 - Selecting local time instead of UTC will now show the correct time 342 everywhere in the program, thanks to Thierry F4DWV. 343 - Show pass duration in minutes in the "Upcoming Passes" dialog. 344 345 346 Changes in version 0.5.0 (29 Jan 2005): 347 348 - It is now possible to specify a minimum elevation for upcoming passes. 349 Passes with max elevation below this limit will be discaded from the list. 350 - Hamlib 1.2.0 support. If compiled with hamlib support, gpredict now 351 requires version 1.2.0 or later and will not compile with earlier 352 versions. 353 - Possibility for other map sizes. Gpredict will automatically detect 354 the size of the map and scale the canvas accordingly. 355 - Improved map display showing QTH, time, upcoming satellite and brief info 356 about a selected satellite. Added buttons for pass prediction for selected 357 satellite. 358 - Satellite lists can be sorted automatically at regular intervals 359 (preferences->lists->autosort). Disabled by default. 360 - Satmap-druid will now open a warning dialog if the number of 361 selected satellites is greater than 10 (bug #555595). 362 - Fixed positioning and alignment errors in AOS prints. Added orbit 363 number to detailed prints. 364 - We now use the standard Gnome data directories (incompatible with 365 previous releases). This means, that the 'configure --prefix=...' 366 and other directory switches should work now. 367 - Replaced obsolete ftime function with gettimeofday. The program should 368 now compile on MacOS X and FreeBSD as well. 369 - Simple and detailed pass predictions can again be saved to text files 370 (bug #839373). 371 - Show rise/set times in Sun and Moon frames. 372 373 374 Changes in version 0.4.0 (17 Apr 2003): 375 376 - TLE files are now stored in user's home directory in 377 $HOME/.gpredict/tle and can be updated automatically at run time. 378 The supplied files are identicale to those at celestrak.com except 379 that the extensions have been changed from .txt to .tle 380 - The tracked satellites are organized in a tree when presented to 381 the user, rather than a flat list. 382 - Updated locations database with more than 2000 known locations 383 with altitude and weather station info. The known locations 384 are now organized in a tree structure. If Hamlib 1.1.3 is available 385 locator squares are calculated as well. 386 - Possibility to have many locations configured and switch between 387 them at runtime. 388 - Possibility to use other maps. Gnome Predict comes bundled with 5 389 different maps, but the user can add and use his/her own maps by 390 copying the images into the $HOME/.gpredict/maps/ directory. The maps 391 will automatically be scaled to 800x400 pixels. 392 - Notebook tabs/labels are only shown if there are at least 393 two modules in the notebook (the user can override it though). 394 - Module names can be up to 50 characters long. 395 - Modules can be deleted and edited after creation (right-click in the 396 iconbar). 397 - Program is safe if a satellite somehow disappears from the database. 398 - Fixed bugs #636186 and #633886. 399 400 401 Changes in version 0.3.2 (24 Jun 2002): 402 403 - No more crash when trying to open a deleted map file 404 (bug #554785). 405 - Number of satellites in the lists is displayed when 406 the user creates a new module (bug #555595). 407 - Updated gpredict.tle 408 - Updated gpredict.pot 409 - Updated da.po (new strings not translated though). 410 411 412 Changes in version 0.3.1 (6 May 2002): 413 414 - Added danish translation. 415 - Fixed bug #551224. 416 417 418 Changes in version 0.3.0 (13 Apr 2002): 419 420 - Configuration is stored using GConf instead of gnome-config. 421 - Default prefix is no longer /usr/local/groundstation 422 - User configuration files are stored in ~/.gpredict/ 423 (previously ~/.groundstation/) 424 - Longitude is in the range of -180 to 180 negative being East of 425 Greenwich. 426 - Get detailed information about any of the upcoming passes. The plot 427 showing a satellite pass can be saved as an image or printed. 428 - New earth map module with the possibility to save and print the map 429 as an image. 430 - Anti aliased graphics giving much better quality. The user can disable 431 this feature if the performance is very poor. 432 - New shortcut bar. 433 - Have as many modules open as your computer can handle. 434 - Disabled the possibility to change the TLE file at runtime 435 (obsolete feature). 436 437 438 Changes in version 0.2.2 (23 Oct 2001): 439 440 - Program can read custom TLE files even at runtime. 441 - New, very flexible functions to predict upcoming passes. 442 - Show/Save/Print/Plot detailed info about the upcoming pass. 443 - Plot the upcoming pass in polar form (Az/El). 444 - Show/Save/Print AOS/LOS times for upcoming passes. 445 - Satellites in the satlist can have different colors for practically 446 any state a satellite can have. 447 - More options in the preferences box. 448 449 450 Changes in version 0.2.1: 451 452 - Just added a sentence to INSTALL about not to 453 use ~ in --prefix=... 454 455 456 Changes in version 0.2.0 (4 Aug 2001): 457 458 - Abandoned client/server interface and included tracking code from Predict 459 directly into the program 460 - Can track a large number of satellites (current limit is at 200, but can be 461 chaged by editing the 'defaults.h' file) 462 - Predict AOS and LOS times for upcoming passes 463 - The user can change the text colors in the satellite list 464 - The user can change the time between satellite list updates
