Gpredict can 263 either notify the user when TLEs are getting too old, or perform automatic 264 update in the background. The network update requires libcurl. 265- Added optional grid lines to the map view (30 deg resolution). 266- Added possibility to show ground tracks on the map (feature request #557586) 267- Added support for the optional operational status of satellites encoded into 268 the satellite names in TLE coming from CelesTrak. 269- Fixed wrong epoch day in the satellite info dialogue (bug #1586341). 270- Polar and Az/El plots of passes in the single-pass dialogue. 271 272 273Changes in version 0.6.1 (5 Sep 2006): 274 275- Fixed bug that caused data to be installed into the wrong directory when using 276 'make install DESTDIR=/foo' (patch #1552216 by Denis Leroy). 277- Fixed bug that caused errors when user deleted the sample ground station while 278 one or more modules were still using it (reported by Hamish Moffatt). 279 280 281Changes in version 0.6.0 (4 Sep 2006): 282 283- New module design: A module is no longer either a list or a map. A module can 284 contain up to three views that can be any combination of map, list, polar and 285 single satellite view. 286- Each module can be configured individually (colours, views, location) or it 287 can use the global default settings. 288- Module have three states: Docked, Window and fullscreen. 289- Improved map view quality and performance with possibility to highlight areas 290 covered by satellites. 291- List View is fully configurable with respect to which columns should be 292 visible. Furthermore, the list view has a lots of new columns. 293- The upcoming passes dialogs can show much more details like TCA, duration and 294 maximum elevation. 295- Context sensitive pop-up menus instead of buttons to access the most important 296 functions. 297- Geographical coordinates can be shown using N, S, E and W suffixes instead 298 og sign. This should settle the debate on whether negative longitude is East 299 or West of Greenwich (I know which one is the correct one ;-). 300- Added support for imperial units (default is still the metric system). 301- Added support for user specified time format strings. 302- No upper limit on the number of satellites. 303- Uses SGP4/SDP4 algorithms for element set propagation. 304- Requires Gtk+ 2.8 or later and GNOME dependencies are gone for good! 305- Gpredict is now much more robust against configuration errors. If something 306 goes wrong you can simply delete all user configuration files and start from 307 fresh. Besides that, gpredict only uses human readable configuration files, 308 which can be edited using a text editor. It should, however, never be necessary 309 to alter the configuration files manually. 310- Draft User Manual and Design Document. 311 312 313Changes in version 0.5.3 (19 Jan 2006): 314 315- Fixed errors when compiling on NetBSD, thanks to Berndt VK5ABN. This patch 316 actually fixes the i18n installation problems on the other platforms too. 317 318 319Changes in version 0.5.2 (22 Dec 2005): 320 321- Fixed errors when compiling without hamlib support. 322 323 324Changes in version 0.5.1 (25 May 2005): 325 326- Selecting local time instead of UTC will now show the correct time 327 everywhere in the program, thanks to Thierry F4DWV. 328- Show pass duration in minutes in the "Upcoming Passes" dialog. 329 330 331Changes in version 0.5.0 (29 Jan 2005): 332 333- It is now possible to specify a minimum elevation for upcoming passes. 334 Passes with max elevation below this limit will be discaded from the list. 335- Hamlib 1.2.0 support. If compiled with hamlib support, gpredict now 336 requires version 1.2.0 or later and will not compile with earlier 337 versions. 338- Possibility for other map sizes. Gpredict will automatically detect 339 the size of the map and scale the canvas accordingly. 340- Improved map display showing QTH, time, upcoming satellite and brief info 341 about a selected satellite. Added buttons for pass prediction for selected 342 satellite. 343- Satellite lists can be sorted automatically at regular intervals 344 (preferences->lists->autosort). Disabled by default. 345- Satmap-druid will now open a warning dialog if the number of 346 selected satellites is greater than 10 (bug #555595). 347- Fixed positioning and alignment errors in AOS prints. Added orbit 348 number to detailed prints. 349- We now use the standard Gnome data directories (incompatible with 350 previous releases). This means, that the 'configure --prefix=...' 351 and other directory switches should work now. 352- Replaced obsolete ftime function with gettimeofday. The program should 353 now compile on MacOS X and FreeBSD as well. 354- Simple and detailed pass predictions can again be saved to text files 355 (bug #839373). 356- Show rise/set times in Sun and Moon frames. 357 358 359Changes in version 0.4.0 (17 Apr 2003): 360 361- TLE files are now stored in user's home directory in 362 $HOME/.gpredict/tle and can be updated automatically at run time. 363 The supplied files are identicale to those at celestrak.com except 364 that the extensions have been changed from .txt to .tle 365- The tracked satellites are organized in a tree when presented to 366 the user, rather than a flat list. 367- Updated locations database with more than 2000 known locations 368 with altitude and weather station info. The known locations 369 are now organized in a tree structure. If Hamlib 1.1.3 is available 370 locator squares are calculated as well. 371- Possibility to have many locations configured and switch between 372 them at runtime. 373- Possibility to use other maps. Gnome Predict comes bundled with 5 374 different maps, but the user can add and use his/her own maps by 375 copying the images into the $HOME/.gpredict/maps/ directory. The maps 376 will automatically be scaled to 800x400 pixels. 377- Notebook tabs/labels are only shown if there are at least 378 two modules in the notebook (the user can override it though). 379- Module names can be up to 50 characters long. 380- Modules can be deleted and edited after creation (right-click in the 381 iconbar). 382- Program is safe if a satellite somehow disappears from the database. 383- Fixed bugs #636186 and #633886. 384 385 386Changes in version 0.3.2 (24 Jun 2002): 387 388- No more crash when trying to open a deleted map file 389 (bug #554785). 390- Number of satellites in the lists is displayed when 391 the user creates a new module (bug #555595). 392- Updated gpredict.tle 393- Updated gpredict.pot 394- Updated da.po (new strings not translated though). 395 396 397Changes in version 0.3.1 (6 May 2002): 398 399- Added danish translation. 400- Fixed bug #551224. 401 402 403Changes in version 0.3.0 (13 Apr 2002): 404 405- Configuration is stored using GConf instead of gnome-config. 406- Default prefix is no longer /usr/local/groundstation 407- User configuration files are stored in ~/.gpredict/ 408 (previously ~/.groundstation/) 409- Longitude is in the range of -180 to 180 negative being East of 410 Greenwich. 411- Get detailed information about any of the upcoming passes. The plot 412 showing a satellite pass can be saved as an image or printed. 413- New earth map module with the possibility to save and print the map 414 as an image. 415- Anti aliased graphics giving much better quality. The user can disable 416 this feature if the performance is very poor. 417- New shortcut bar. 418- Have as many modules open as your computer can handle. 419- Disabled the possibility to change the TLE file at runtime 420 (obsolete feature). 421 422 423Changes in version 0.2.2 (23 Oct 2001): 424 425- Program can read custom TLE files even at runtime. 426- New, very flexible functions to predict upcoming passes. 427- Show/Save/Print/Plot detailed info about the upcoming pass. 428- Plot the upcoming pass in polar form (Az/El). 429- Show/Save/Print AOS/LOS times for upcoming passes. 430- Satellites in the satlist can have different colors for practically 431 any state a satellite can have. 432- More options in the preferences box. 433 434 435Changes in version 0.2.1: 436 437- Just added a sentence to INSTALL about not to 438 use ~ in --prefix=... 439 440 441Changes in version 0.2.0 (4 Aug 2001): 442 443- Abandoned client/server interface and included tracking code from Predict 444 directly into the program 445- Can track a large number of satellites (current limit is at 200, but can be 446 chaged by editing the 'defaults.h' file) 447- Predict AOS and LOS times for upcoming passes 448- The user can change the text colors in the satellite list 449- The user can change the time between satellite list updates 450
